CFD Simulation for Flow over Passenger Car Using Tail Plates for Aerodynamic ...IOSR Journals
This work proposes an effective numerical model based on the Computational Fluid Dynamics
(CFD) approach to obtain the flow structure around a passenger car with Tail Plates. The experimental work of
the test vehicle and grid system is constructed by ANSYS-14.0. FLUENT which is the CFD solver & employed in
the present work. In this study, numerical iterations are completed, then after aerodynamic data and detailed
complicated flow structure are visualized.
In the present work, model of generic passenger car has been developed in solid works-10 and
generated the wind tunnel and applied the boundary conditions in ANSYS workbench 14.0 platform then after
testing and simulation has been performed for the evaluation of drag coefficient for passenger car. In another
case, the aerodynamics of the most suitable design of tail plate is introduced and analysedfor the evaluation of
drag coefficient for passenger car. The addition of tail plates results in a reduction of the drag-coefficient
3.87% and lift coefficient 16.62% in head-on wind. Rounding the edges partially reduces drag in head-on wind
but does not bring about the significant improvements in the aerodynamic efficiency of the passenger car with
tail plates, it can be obtained. Hence, the drag force can be reduced by using add on devices on vehicle and fuel
economy, stability of a passenger car can be improved.
Drag Reduction of Front Wing of an F1 Car using Adjoint Optimisationyasirmaliq
The Project Poster summarizes the aims and objectives of the Final Year Dissertation. The project starts with a detailed study on the parameters that tend to affect the performance of front wings of an F1 car and goes through designing the front wings(3) with endplates and wheel, meshing it, solving/analysing the flow and finally optimising the selected geometry using Fluent Adjoint Solver for efficient performance.
Adjoint optimisation technique is used to achieve optimal performance from the front wings. It's the most successful shape optimisation method as it's independent of the number of design variables exponentially reducing computational time and cost. The emphasis has been put on optimising the shape of the front wings using the Adjoint method as it’s the most efficient and computationally inexpensive method for design optimisation. The approach towards shape optimisation is downforce constrained drag minimization as it would result in keeping a constraint on downforce and reducing the drag at the same time, thus producing optima for a given downforce/drag value.

Design of Rear wing for high performance cars and Simulation using Computatio...IJTET Journal
The performance of a sports car is not only limited to its engine power but also to aerodynamic properties of the car. By decreasing the drag force it is possible to reduce the engine power required to achieve same top speed thus decreasing the fuel requirement. The stability of a sports car is considerably important at high speed. The provision of a rear wing increases the downforce thus reducing the rear axle lift and provides increased traction. In this study an optimum rear wing is designed for the high performance car so as to decrease drag and increase downforce. The CAD designed baseline model with or without rear wing is being analyzed in computational fluid dynamics software. The lift and drag coefficient are calculated for all the design thus an optimum rear wing is designed for the considered baseline model.
STUDY OF AERODYNAMIC DRAG OF TWO DRAFTING FORMULA ONE RACING CARSSomnath Saha
There is an optimum strategy for Formula One racing team time trials, which is not only depended on engine efficiency but also on the body geometry, vehicle sequence and the resulting aerodynamic drag. In race track, trailing car always tries to stay at the slipstream (low pressure area) created by the leading car (also called slipstreaming or drafting). If a car follows the leading car moving at the same speed than the rear car will require less power to maintain its speed. This strategy later helps in overtaking in the pit lane or famously called undercutting. This paper reviews the result of CFD simulations of two drafting Formula one racing cars. Here for a succinct study two cars are considered, the leading and the trailing car. CAD models for the same were created with the separation distances of d = 0.25m, 0.5m, 1m, 3m, and 5m. CFD simulation is done in ANSYS Fluent software with the standard k–ε model for closure. The main purpose of this study is to explain the aerodynamic drag effects by means of the detailed pressure distribution on and around the cars and shown how both the drafting cars significantly influence the pressure distribution on each other’s body and the static pressure in the region between them, which governs the drag reduction experienced by car.
Aircraft Finite Element Modelling for structure analysis using Altair ProductsAltair
The Airbus airframe design process has considerably evolved since 20 years with the constant improvement of numerical simulation capability and the computational means capacity. Today the size of Finite Element Models for aircraft structural behaviour study is exceeding the boundary of airframe components (fuselage section, wing); for the A350, a very large scale non-linear model of more than 60 million degrees of freedom has been developed to secure the static test campaign. This communication will illustrate the partnership with Altair and the use of Altair products for the creation and verification of very large models at Airbus. It will deal with: - Geometry preparation - Meshing - Property assignment - Assembly - Checking More generally, numerical simulation will play more and more a major role in the aircraft process, from the development of new concepts / derivatives to the support of the in-service fleet. Then, this presentation will also state the coming needs regarding model creation tools to cope with Airbus strategy.

Automating 1D/3D CFD analysis workflows – Speed up design exploration of a Y-...Siemens PLM Software
This study aims to leverage multiple Siemens PLM solutions in order to allow you to cover your entire design workflow, from design variants to automated post-processing of results. HEEDS, Siemens PLM’s industry-leading process integration and design optimization (PIDO) tool, was used in order to automate the modification of a parametric CAD geometry in STAR-CCM+.
It was then used in order to very simply set-up a workflow involving a 1D/3D CFD coupling between Simcenter Amesim and STAR-CCM+. This co-simulation produced results which were automatically post-processed from HEEDS: 1D plots traced directly in HEEDS, and post-processing scenes created in STAR-CCM+ were automatically populated and collected in HEEDS.
This approach allows you to automate the creation, simulation and post-processing of your design configuration sets while minimizing friction and required effort on your part.

“MATERIAL AND STRUCTURE OPTIMIZATION AND VALUE ENGINEERING APPLIED TO CAR DOO...Jayesh Sarode
In this project automobile window regulator is selected as a case study for the use of optimization technique in engineering design. This is a project of the work performed towards the stiffness optimization of an automobile window regulator.
The aim of the project is to analyze the car window regulator with presently used material steel and replacing with Plastic if Possible. Also we are going to reduce weight of the window by using Plastic materials replacing with steel. The aim is to achieve the essential function at the lowest overall cost while maintaining optimum value assurance. In this project, the Car window regulator modeled using software CATIA.
This project intends to explore the adoption of Value Engineering (VE) as a value creation tool. This project presents the basics of Value Engineering and its different phases that can be implemented to a window regulator for its optimization. Value Engineering can improve the product cost by reducing the unnecessary costs associated with the product.
My long term goal is to postulate and validate design metrics which effectively and efficiently measure the remanufacturability of given designs. As well as identifying existing re manufacturing guidelines, philosophies, and practices.
