The objective of present study is to compare the flow characteristics around moving bodies near the ground. The influence of the gap height and ground conditions, the moving and fixed grounds, on the aerodynamic forces as well as the dynamic behavior of the wake flow around the square cylinder near a ground is investigated. The model wind tunnel experiments were carried out in an open circuit low turbulence subsonic wind tunnel. The wind tunnel is equipped with moving belt system to simulate the ground effect. The mean velocity and the turbulent field around a square cylinder were measured using a two-component Particle Image Velocimetry (PlV). From the velocity profiles in wake region, the pressure recovery on a moving ground decreases due to the high momentum supply, finally causing the drag to increase from the fixed ground, while the lift has opposite pattern. Through the full scale wind tunnel testing, aerodynamic force difference occurs under ground conditions and increases as yaw angle increases. Therefore the adequate ground simulation is necessary to enhance the control stability under the transient crosswind.
