Abstract
A numerical analysis has been performed for the simultaneously developing laminar flwo and temperature fields in the entrance region of a semi porous channel with both symmeric and asymmetric heating. The vorticity-velocity method with the power law scheme is employed to solve the governign equations for the flow and temperature fields. A coordinate transformation technique is used to handle the boundary condition far downstream. The effects of wall suction and heating are examined. The local friction factor and Nusselt number are presented as a function of axial position, and it is seen that they are strongly affected by the wall suction and heating. When wall suction is strong enough, flow reversals are observed. Comparisons with existing theoretical and experimental results are also presented.
