The paper presents a numerical solution for laminar fluid flow and heat transfer of a liquid metal in the entrance region of a rectangular channel with solid fins which are arranged on the top and bottom isothermal walls in a periodically staggered way. This arrangement simulates a compact heat exchanger. The governing equations are solved by a power-law scheme. The velocity and pressure terms of the momentum equation are solved by the SIMPLER method. The results demonstrated that the fins interrupt the boundary later and cause a detachment from the wall forming a recirculation zone in front of the fin, thus leading to a reattachment point with a relatively high Nusselt number. It is observed that increasing the fin height affects the heat exchanger design in two opposing ways, namely, a higher Nusselt number and increasing the pressure drop. It is also understood that the location of the periodically fully developed region is sensitive to both the Reynolds number and the Peclet number.
