摘要

Three-dimensional simulations of laminar separated and reattached flow and heat trans- fer over a blunt flat plate in a square channel are presented. Numerical calculations of Navier-Stokes equations and energy equation are carried out using the finite difference Method. Results of three-dimensional calculation are compared with two-dimensional Ones and effects of the side walls are described. It is clarified from the present results that The reattachment length increases with an increase of Reynolds number and the flow in the Recirculation region becomes three-dimensional.
