Three-dimensional simulations of an unsteady separated and reattached flow and the heat transfer over a blunt flat plate are presented. The Reynolds number used is 5000. The vortices shed from the reattachment flow region have a hairpin-like structure. These large-scale vortex structures greatly influence the heat transfer in the reattachment region. The present results are compared with the previous three-dimensional calculations at a low Reynolds number and there is no essential difference between the two results with respect to flow structure. The reattachment length is about five plate thicknesses, which is the same as that observed in previous experiments. The velocity distributions and turbulent intensities are in good agreement with the experimental data. However, the Nusselt number and temperature distributions are different from the measured ones.
