Abstract: Large eddy simulations (LES) are used to study passive flow control for drag reduction in a simplified ground vehicle. Addon devices in the form of short cylinders are used for the formation of streaks in the streamwise direction that lead to the separation delay. The results of the present numerical simulations are compared with the experimental data and show good agreement. The twostage flow control mechanism is analyzed from the LES results. It was found to be in agreement with the previous experimental observations that the counterrotating vortices behind the impinging devices influence the separation only indirectly through the longitudinal vortices further downstream.
