Heat transfer in laminar plane channel flow with uniform suction or injection
Abstract
Heat transfer is studied in a developed laminar incompressible flow with constant properties within a two-dimensional channel with porous walls having a constant temperature. Several asymptotic solutions of the energy equation are obtained for small and large wall Peclet numbers and large Prandtl numbers (much greater than 1), which can be used to establish a correlation between the relative heat transfer coefficient and the suction parameter. The computed results of the local Nusselt number distribution in both the thermal stabilization and channel entrance regions are generalized for all Prandtl numbers by a single relation expressed in the form of the relative heat transfer law.
