On forced convective heat transfer for a stokes flow in a wavy channel

Study of heat transfer in a two-dimensional wavy channel due to a pressure driven Stokes flow, normal to the wall corrugation, is made. Expression for the mean Nusselt number describing the average rate of heat transfer from the warmer surface, obtained analytically, predicts a decreased heat transfer rate due to corrugations. This observation is found to be significantly opposite to the prevailing results of moderate or large Reynolds number flows.
