The flat plate aspect ratios (t/c, t: plate thickness, c: plate chord length) are set to be 0.01, 0.025, 0.05, and 0.1. The Reynolds numbers based on the plate thickness (Ret ) are set to be 250 (laminar reattachment), and 1, 000 (turbulent reattachment). The results suggest that the effects of t/c can relatively be negligible at Ret = 250. After formation of three-dimensional turbulent structures at Ret = 1, 000, however, the reattachment points move to downstream as t/c decreases. In this Ret , the flow fields characteristics such as instantaneous flow, turbulent kinetic energy, and boundary layer near the leading edge are different depending on t/c.
