A numerical analysis based on the finite difference method is made on a three-dimensional unsteady separated and reattached flow around a surface-mounted hexahedron in a channel with two parallel walls, and the heat transfer characteristics therein are also analyzed. Reynolds number treated is 1000 and Prandtl number 0.7, respectively. At Re=1000, the horseshoe vortex becomes unsteady in the vicinity of the side surface, and the shear layer separated from the front corner rolls up and the vortex is shed to the downstream. Futher, it is clarified that the vortices are periodically shed from the side corner. It is also shown that on the side, top and rear surfaces, the local Nusselt number varies with time originating from the vortex shedding, but the local Nusselt number on the front surface exhibits no essential variation with time.
