In this study / reliability and performance of turbulence models used in CFD softwares to determine the aerodynamics of passenger cars, are tested and compared.
In the analyses, drag forces acting on the car, pressure and velocity distributions and wake flow patterns are determined by using several turbulence models with a commercial software Fluent. Calculated results compared to the experimental results given in the literature.
It is observed that, turbulence models give relatively reliable results for determining aerodynamic properties of the model car. Among the turbulence models, RNG k-&epsilon / and standard k-&omega / models stand one step ahead of the other models according to results.
