We investigate the flow characteristics around a series of rectangular bodies (40 d ×80 w ×80 h , 80 d ×80 w ×80 h and 160 d ×80 w ×80 h) placed in a deep turbulent boundary layer. The study is aiming to understand the surface pressure distribution around the bodies such as the suction pressure in the leading edge, when the flow is normal, which is responsible for producing extreme suction pressures on the roof. The experiment includes wind tunnel work by using HWA (Hot-Wire anemometry) and pressure transducers. The experiments are carried out at three different Reynolds numbers, based on the velocity U at the body height h, of 2.4×10 4 , 4.6×10 4 and 6.7×10 4 , and large enough that the mean flow is effectively Reynolds number independent. The results include the measurements of the growth of the turbulent boundary layer in the wind tunnel and the surface pressure around the bodies.
