Simulation of Flow around a Bus with Active Drag Reduction Systelft

A simulation of a bus model dimensions 200 x 50 x 50 mm was conduc~ using CFD software FLUENT 6.2, in order to investigate the flow around a bus with active drag reduction system. Simulations were carried out for the base model which is the refrence point and two other spoiler models A & B. A...
