To study the Aerodynamic Effects of Spoiler of a Car (Sedan – Segment) using Computational Fluid Dynamics
Keywords:Automotive industry, Aerodynamics, ANSYS Fluent, Spoiler of a car, Lift
Aerodynamic is an important aspect in consideration with regard to automotive design. Efficient diagnosis of aerodynamic forces’ effect on a car body becomes necessary when automobiles run at very high speed. In recent days, almost all automobile products coming into the market are designed considering the effect of aerodynamic forces.
The objective of this analysis is to simulate the flow of air over a car body and to estimate the effect of aerodynamic forces like drag and lift. The prediction of drag becomes necessary for vehicle running at higher speeds, may lead to higher fuel consumption, dropping the efficiency. The induced “LIFT” will disconnect wheels and road, which may lead to accidents. The current analysis we are performing, will analyze the effect of these forces on car, with and without spoiler, to understand the spoiler’s presence helping in reducing the drag and its contribution to increase the efficiency of the car. Hypermesh is used for pre-processing and ANSYS Fluent is used as a solver and post processor.
