MIXED CONVECTION AND FLOW-REVERSAL IN A DIFFERENTIALLY AND ASYMMETRICALLY HEATED VERTICAL CHANNEL: APPLICATION TO CONVECTION COOLING OF CIRCUIT BOARDS

Abstract

A mathematical model for mixed convection heat transfer in a vertical channel with asymmetric wall temperatures counting situations of flow-reversal was presented. The model is firstly validated by considering numerical simulations of some test cases problem of mixed-convection available in the literature and then adapted to handle the problem of convection cooling of circuit boards
