CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

4. The main sources are wind energy,
solar power and hydroelectric power
(including tidal energy, which uses
ocean energy from the tides in the
sea). Solar and wind power are able
to be produced on a small scale at
people’s homes or alternatively,
they can be generated on a larger,
industrial scale.
5. The six most common forms are as follows:
1. Solar Power
2. Wind Power
3. Hydropower
4. Geothermal Energy
5. Biomass
6. Biofuels
6. Solar Power
This common renewable, green energy
source is usually produced using
photovoltaic cells that capture
sunlight and turn it into
electricity. Solar power is also used
to heat buildings and for hot water
as well as for cooking and lighting.
Solar power has now become affordable
enough to be used for domestic
purposes including garden lighting,
although it is also used on a larger
scale to power entire neighbourhoods.
7. Wind Power
Particularly suited to offshore and
higher altitude sites, wind energy
uses the power of the flow of air
around the world to push turbines
that then generate electricity.
8. Hydropower
Also known as hydroelectric power,
this type of green energy uses the
flow of water in rivers, streams,
dams or elsewhere to produce energy.
Hydropower can even work on a small
scale using the flow of water
through pipes in the home or can
come from evaporation, rainfall or
the tides in the oceans.
Exactly how ‘green’ the following
three types of green energy are is
dependent on how they are created…
9. Geothermal Energy
This type of green power uses thermal
energy that has been stored just under
the earth’s crust. While this resource
requires drilling to access, thereby
calling the environmental impact into
question, it is a huge resource once
tapped into. Geothermal energy has been
used for bathing in hot springs for
thousands of years and this same
resource can be used for steam to turn
turbines and generate electricity.
10. Biomass
This renewable resource also needs
to be carefully managed in order to
be truly labelled as a ‘green
energy’ source. Biomass power
plants use wood waste, sawdust and
combustible organic agricultural
waste to create energy. While the
burning of these materials releases
greenhouse gas these emissions are
still far lower than those from
petroleum-based fuels.
11. Biofuels
Rather than burning biomass as
mentioned above, these organic
materials can be transformed into
fuel such as ethanol and biodiesel.
Having supplied just 2.7% of the
world’s fuel for transport in 2010,
the biofuels are estimated to have
the capacity to meet over 25% of
global transportation fuel demand by
2050.
