AN ANALYSIS OF CONJUGATE HEAT-TRANSFER FROM A HEATED WALL IN A CHANNEL WITH ZERO-MEAN OSCILLATORY FLOW FOR SMALL OSCILLATORY FLOW REYNOLDS-NUMBERS

An exact solution for small oscillatory flow Reynolds numbers is prese nted for the fully-developed zero-mean oscillatory flow and heat trans fer in a two-dimensional channel with a wall uniformly heated to simul ate the forced-convection cooling of electronic components on printed circuit boards. The other channel wall is insulated and all thermal pr operties are taken to be constant. Also, results are given in terms of time-averaged Nusselt number as functions of oscillatory flow Reynold s number and Wormersely number, based on both channel height and tidal displacement as the characteristic lengths, and for two specific case s with air and water as the cooling fluid media.
