• Some characteristics of flow pattern and local heat transfer past a circular cylindrical cavity in a turbulent boundary layer on a flat plate have been studied changing the cavity shape H/D=0.1〜1.0(H : cavity height, D : cavity diameter) in the range of Re=4.1×10^4〜1.1×10^5. It is made clear that there are two unstable flow behaviors, that is, flapping flow and switching flow, and that the additional pressure drag and the average heat transfer coefficients on the side wall and the bottom surface show a maximum value in the case of H/D=O.5,and then in this cavity, a slant recirculating eddy is formed and this flow behavior is assymmetric.
