Краткое описание

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 directly solve Navier-Stokes equations and energy one, and resulting finite difference equations are solved with the SMAC method in Reynolds number range from 100 to 500 for fluid of Prandtl number 0.7. Present numerical results are compared with the flow visualization ones and it is found that the present numerical method well simulates the observed results such as horseshoe vortices and the recirculating flow. Heat transfer coefficient greatly varies on the different side surfaces of blocks and also with Reynolds number.
