Numerical results simulating a three-dimensional laminar separated flow and heat transfer around staggered surface-mounted rectangular blocks in a plane channel are presented. Treated in the present study is a case of staggered three-row blocks. The finite-difference method is employed to solve the Navier-Stokes and energy Equations directly, and the resulting finite-difference Equations are solved with the SMAC method for Re = 100–500 and Pr = 0.7. The present numerical results are found to simulate well the visualization results such as horseshoe vortices and recirculating flow. The heat transfer coefficient greatly varies on the different side surfaces of blocks and also with Reynolds number.
