Popis:	Numerical results simulating a three-dimensional separated flow and heat transfer around surface-mounted rectangular blocks in a plane channel are presented. Flow configuration treated in the present study is transversal two blocks. The finite difference method is employed to directly solve Navier-Stokes, continuity and energy equations, and resulting finite difference equations are solved with the SMAC method in Reynolds number range from 100 to 500. Present results are compared with available flow visualization ones and it is found that the present numerical method well simulates the observed results such as horseshoe vortices and the recirculating separated flow. Local and mean heat transfer characteristics are clarified and their correlations with the flow structure are investigated.
