Abstract

Vortices formed around the A-pillar region dictate the pressure distribution on the side panels of a passenger vehicle and also can lead to aerodynamic noise generation. This paper analysed and compared qualitative flow visualization of airflow behavior based on the A-pillar region. Two simplified vehicle models with different A-pillar geometry were simulated using Computational Fluid Dynamics (CFD) under laboratory operating conditions. Commercial software (SWIFT) was used. In SWIFT, the simplified vehicle model was generated using Fame Hybrid. CFD simulations were carried out using SWIFT under steady state conditions using the HTM2 turbulence model. Investigations were carried out at velocities of 60, 100 and 140km/h and at 0, 5, 10 and 15 degree yaw angles. Results of Cp values were also compared against available experimental data. Results obtained using CFD modeling provided reasonable agreement against available experimental data.
