Three-dimensional simulations of laminar separated and reattached flow and heat transfer over a blunt flat plate in a channel are presented. Numerical calculations of Navier-Stokes equations and energy equation are carried out using the finite difference method. The results of three-dimensional calculations are compared with the two-dimensional ones, and show the effects of the endwall. It is clarified from the numerical results that the reattachment length increases with Reynolds number and the flow in the recirculation region becomes three-dimensional. The reattachment line is curved by the endwall effects. Two-dimensionality of the flow is reduced as Reynolds number increases. The horseshoe vortex near the endwall greatly influences the heat transfer in the redeveloping flow region.
