Abstract

The current study investigates different methods to minimize the drag coefficient (C(D)) without ignoring the safety factor related to the stability of a vehicle, i.e., the lift coefficient (C(L)). The study was carried out by employing an SUV car analyzed numerically using one of the CFD software, Ansys. Four different models such as realizable k-ε, standard k-ω, shear stress transport k-ω, and Reynolds stress model (RSM). The considered models have been validated with experimental data and found in good agreement. The considered inlet velocity varies from 28 to 40 m/s, the results showed that the drag coefficient and the stability are both improved by applying a modification on the roof of the considered car.
