Effect of rotating wheel and moving ground is investigated by using full scale wind tunnel test and current state-ofthe-art CFD technique. S2A wind tunnel located in St-Cyr, France and commercial CFD software based on Lattice Boltzmann Method were used for wind tunnel test and CFD simulation, respectively.
Total 6 vehicles were tested in the wind tunnel for both static (fixed wheel and fixed ground) and mobile (rotating wheel and moving ground). For the deep understanding of ground effect, air flow simulations were conducted for 2 hatch back vehicles. Rotating wheel and moving ground were implemented by using sliding mesh technique and applying tangential velocity to the ground, respectively. It was shown that rotating wheel increases wheel drag, while moving ground decreases vehicle body drag by restructuring rear wake. It was concluded that ground effect strongly relies on wheel shape and wake structure.
