Benefits of Intel Technologies for Engineering SimulationAnsys
This presentation gives the perspective of an ISV (independent software vendor) on the usage of the latest Intel technologies for engineering simulation. It starts off with introducing ANSYS and why our customers have a continually increasing need for higher computing performance so that they can run faster, bigger, and more simulations. In order to meet this continually growing compute demand, it demonstrates how we have worked closely with Intel to optimize our software at different scales of parallelism (from workstation, server-based clusters to supercomputers). Key strategies to enable efficient parallel execution are discussed, and recent examples of the value of software optimization are shown.
Simulation-Based Engineering for Satellite ApplicationsAnsys

The powerpoint describes air velocity plot of the bike that shows air molecules motion out of the way as it travels through the air. As millions of air molecules approach the front of the bike, they begin to compress, and in doing so raise the air pressure in front of the bike. At the same time, the air molecules travelling along the sides of the bike are at atmospheric pressure, a lower pressure is compared to the molecules at the front of the bike. The study for the angle of solar panel mounting position is conducted. The optimized angle is decided for the design. A angle of panel and vehicle efficiency relationship is correlated.
The purpose of this research work is to study the hydrodynamic characteristics of a new type of artificial reef structure, in order to provide a structure with low flow resistance, which will be a more suitable shelter for fishes and marine organisms. The idea of the new artificial reef is based on the streamlined bicycle helmet design concept. The hydrodynamic characteristics of the helmet and hollow cube artificial reefs (ARs) of the same volume have been studied at different water depths and wave frequencies of Malaysia seas using Computational Fluid Dynamics (CFD) method. The finite volume RANSE code Ansys CFX was used for calculating the reefs drag force (FD) and flow characteristics, while the potential flow code Ansys Aqwa was used for calculating the reefs inertia force (FI). The Shear Stress Transport (SST) turbulence model was used in the RANSE code. The results of the two ARs were then compared for studying the hydrodynamic improvement due to the use of streamlined helmet artificial reef on the flow pattern around it. The streamlined body of the helmet artificial reef enhances the flow pattern at the aft region of the reef and provides flow zones with moderate flow speed at this area, which can help fishes and marine organisms from finding good shelter. The special shape of the different openings in the body of the helmet artificial reef improves the condition of the flow velocity distribution inside the unit than that of the hollow cube unit, which can increase the amount of the nutrient to the living fishes and organisms inside the reef.
The purpose of this study is to evaluate the reception of the GPS signal of a Telematics Electronic Control Unit
(ECU) in two different cabin geometries. In the first cabin, the ECU is installed in the center of the dashboard. In
the second cabin, the ECU is installed in two different positions: 1-Near the center of the dashboard and 2- On the
right side of the dashboard.
For increasing the efficiency of the system, extended surfaces like fins are used. The heat transfer rates of different
shapes and cross sections like circular, rectangular, T-shaped and Tree shaped fins is compared. As per the data considered
from the previous works the heat transfer rate is depending on the surface area and the heat transfer coefficient,
the surface area is increasing from circular to tree shaped fins. In this paper temperature distribution of the tree shaped
fins is investigated by changing bifurcation angle, adding an extra element and the fin materials. Different cross section
of the elements is considered and will be validated.
Thermal analysis is enhanced by using Computational Fluid Dynamics ANSYS Workbench 15. Analysis will be done for
different working conditions.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
Understanding Inductive Bias in Machine LearningSUTEJAS

The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
This presentation will be approximately 25 minutes, leaving 5 to 10 minutes for Q&A. Claearly explain each slides and do not fly over them. A very enthusiastic tone is needed!
This section describes example of positive return on investment from CFD. The examples are specifically chosen to cover a wide range of applications.
Measuring the ROI of a tool used in the development process is not always straightforward. In this presentation, we are presenting the ROIs using different point of view.
First, we will show the advantages and cost-savings of using CFD simulation both early and often during the development and the advantage this approach has when combined to traditional physical testing.
Then, we will give indication on how YOU can measure the possible returns on investment of using CFD. Our experience shows that, for any of your company, CFD can be a critical tool to shave time and cost to your development process.
But CFD simulation is not about determining the performance of one design. CFD simulation can be used very effectively to identify the best design, to make trade off between performance, quality, and costs, to perform “what-if” analysis.
Furthermore, CFD simulation can avoid costly product failure as well as downtime. With CFD, you can test your products to the extreme as well as design AND TEST better performing systems without even shutting them down.
Lastly, we will examine the cost of accuracy: the cost of not using the correct tool to perform your CFD simulation.
The great advantage of using CFD simulation during your development cycle is that you can use it before a single prototype is even built.
- You can literally gain insight into your product performance as the first “raw” drawings are being completed.
- You can test initial ideas and configurations at the click of a mouse
As the design is refined, you can continuously:
- refine your understanding of your product behavior
- continuously virtually test possible variation of the design to find the highest performance design
- run “what-if” analysis to test alternative to the current design
But no product is used in exactly the same manner. With CFD simulation, you can test 100’s of way your product is being used, thus making sure your design is robust, however your clients will use it.
With CFD, there is no compromise between better time-to-market or improved quality. With CFD, you can achieve both.
The following slide shows this graphically.
This is about describing the graph to make sure attendees understand it. Spent 2 to 3 minutes if needed!
First list the different design phase. It is important to group them in 3 categories
- Phase 1: design before prototyping
- Phase 2: physical testing
- Phase 3: production ramp up.
Notice how the cost of a design change increase as you move through the development phase. By the time you reach the prototyping phase, design change cost are already extremely high.
By using simulation early and often, you can optimize the design during the concept phase and perform design changes at a very low costs. CFD and simulation helps solving problems early in the design phase, where problems can easily, quickly, and cheaply be fixed. Other method like CAD and traditional analysis or physical testing only only occurs later in the design phase, where costs are extremely large.
Furthermore, with CFD, you can test a large number of designs, compared to physical testing.
Consider the experience of U.S.-based Weil-McLain, a leader of space conditioning and water heating systems.
When developing an advanced three-pass, horizontal-flue boiler, the company’s engineers used CFD software to analyze fluid flow patterns and heat transfer of different boiler designs. By helping them to speed up the usually tedious process of evaluating design iterations, CFD software cut more than six months from the company’s typical time to market using conventional build-and-test methods — but not at the expense of reaching the product’s key performance and quality targets. The new Weil-McLain boiler featured design improvements that boosted efficiency to more than 86 percent, making it one of the most efficient units of its kind.
time-to-market savings took place at AcoustiFLO, LLC, a specialist in custom fan engineering in the U.S.
For an efficient new centrifugal fan module that could drop into packaged air handlers, the company’s engineers used CFD software to evaluate the interaction between the fan’s diffuser and impeller in many different design variants. By helping the investigating team find an optimal design quickly, CFD pared more than six months from the company’s usual development cycle.

When a product failure incident occurs, the consequences can mount up: loss of profits, repair costs, fixed and variable operating costs wasted during downtime, and a myriad of other costs that reverberate throughout the business. The damage can be measured in dollars — millions in lost profit per year — as well as in reputation, enough to send a company to bankruptcy.
For example, in chemical process equipment, flow fields can be very complex and difficult to measure. Troubleshooting or improving efficiency requires multiple data points, which are often unavailable. To reduce downtime and loss of revenue, CFD can be invaluable at virtually analyzing equipment at full scale. Fluid dynamics analysis provides an inside look into the function and operation, offering valuable information to equipment manufacturers, plant managers, production managers, process engineers, and research and development staff.
Here we insist on the cost of taking such an intalation off-line to troble shoot and test different solution. Thanks to CFD, the only downtime needed is to modify the system, not for testing – all tests and desgin validations are done virtually. All information is on the slide

On the warranty front, India-based Control Components Inc. (CCI) faced accelerating warranty costs related to its turbine bypass valves. Power plants today operate at supercritical conditions to meet fluctuating power demands, which places added strain on the valves. CFD simulation made it possible to quickly upgrade the turbine bypass valve in a few weeks, compared to the six to 12 months that would have been required using conventional methods.
Reduced warranty costs
Power plant valves undergo much more thermal and mechanical loading than originally designed for. CCI used ANSYS CFX to simulate valve fl ow parameters, such as pressure (shown), at harsh operating conditions. This information was used to design structurally stronger components that can be installed in a simple field retrofi t to existing valves.
One of CFD’s overlooked cost benefits is its ability to improve speed and quality of the design optimization process. Even when designing the simplest products, today’s engineers must optimize a multitude of geometry, material and other design attributes. A seemingly straightforward flap valve design, for example, might involve dozens of subtle changes to the geometry of the valve body or fl ap. A more challenging fluid flow application, such as optimizing the aerodynamics of a Formula One car, might require many hundreds of changes.
The most advanced CFD simulation products increasingly contain features that eliminate the time-consuming, error prone process of manually evaluating incremental design variations. Key among these features is the automated generation of parametric design variations, which dramatically speeds up the user’s ability to evaluate multiple what-if scenarios without the need for manual rework.
Other tools allow users to evaluate the effects of variations within a given design tolerance or determine which design parameters require the tightest control. Still other features automate statistical optimization methods, including design of experiments (DOE) and Six Sigma analysis. A CFD suite with integrated tools can help users to understand which parameters the design is most sensitive to as well as determine which design parameters require the tightest control. For the most innovative and fastest results, all optimization techniques should take place within a single-user environment.
As an example of design optimization at its best, Dyson in the U.K. set about developing a revolutionary bladeless fan without benefit of previous experience with this type of design.
Historically, the company relied on physical prototyping, but engineers faced evaluating hundreds of design candidates to optimize this new product. After testing a concept prototype, the goal was to increase the amplification ratio to move the maximum amount of air possible for a given size and power consumption. Using simulation, Dyson’s engineers steadily improved the amplification ratio performance to 15 to one, a 2.5-fold improvement over the six-to-one ratio of the original concept design.

Consider turbomachinery design, which is highly complex and demanding. Bharat Heavy Electricals Limited (BHEL), a large energy-sector organization in India, needed to improve performance of one of its utility steam turbines. Engineers there used CFD to analyze similar turbine designs to acquire insight into the flow parameters for each stage and into loss coefficients for the inlet and outlet passage sections — a task that would have been impossible without simulation tools.

Fast and Reliable CFD Solutions
Race teams use simulation software to evaluate many different race conditions and car configurations. These different race parameter may only improve overall speed by fractions of a second but, that often means the difference between winning and second place.
The leading teams around the world have found that ANSYS delivers the most reliable

Unfortunately, not all CFD products are created equal when it comes to accuracy. Modern CFD software, for instance, always contain a turbulence model, but differences in how those models have been implemented in software can have a dramatic effect on accuracy. Because the factors that drive accuracy can be somewhat opaque to users and difficult for non-specialists to grasp, the best advice is to work with established CFD vendors whose software has been thoroughly validated in the widest variety of real-world applications.

Note the significant influence of selecting the right turbulence model (in this case SAS). A CFD code user must think in terms of tick-boxes of which model is available in which code; he also must also consider implementation integrity and the CFD supplier’s underlying know-how behind the technology.

Now that engineering organizations have gained experience and confidence in CFD and related simulation technologies, they increasingly rely on virtual prototyping strategies that drastically reduce the need for physical models and testing. In some applications, CFD and coupled simulations have replaced nearly all of the physical testing. In others, simulation acts as a gatekeeper to allow fewer design concepts to pass through to the physical testing stage.
Either way, any reduction in physical prototyping and testing will remove cost from the design and development process. How much cost? It depends on the application, but tests on even lab-scale mixing equipment can cost hundreds of dollars per hour. Testing full-scale automotive or aerospace models in wind tunnels can run thousands per hour. And neither of these examples includes the cost of producing the physical prototype or analyzing test data.

For example, computer modeling and simulation are helping researchers develop innovative respiratory drugs in a shorter amount of time. The cost of developing a respiratory therapy drug for asthma is estimated at more than $1 billion; the process can take up to 14 years and involve thousands of patients in clinical studies. At Belgium-based FluidDA, in silico respiratory studies employ fluid dynamics simulation to generate accurate images of pulmonary functions, such as airway volume and resistance for individual patients. The impact on development costs and time could be stunning.

In Germany, Voith Turbo used CFD to develop quieter fans by simulating a complete railcar cooling system. Increasingly stricter exhaust regulations and growing output requirements call for higher and higher cooling performance, which could lead to greater noise pollution. The company developed a plan to address these competing parameters in the rail industry. Currently, depending on the stage of product development, Voith is able to reduce its prototype costs by two-thirds.
