AUTOMOTIVE COMPUTATIONAL FLUID DYNAMICS SIMULATION OF A CAR USING ANSYS

In this paper, ANSYS CFX method is used to simulate a single car model with and without a spoiler and by using two types of mesh. The solution of the Reynolds average Navier Stokes equations (RANS equations) has been achieved by using two models such as K-Epsilon and K ?Omega Turbulence model will be analysed. In this report, mesh quality, boundary layer and turbulent y+ value simulation has been thoroughly analysed and solution for both the models has also been compared and discussed the results. We use the ANSYS software to determine the drag and lift forces at different turbulence kinetic energy variables k-Epsilon and K-Omega for the given vehicle domain. Further, the effects of aerodynamic are verified with and without the spoiler.
