Book Description

Natural convection in a side or differentially heated cavity is a classical problem in heat transfer. The problem represents a wide range of engineering applications and has also been commonly used as a benchmark problem for validating Computational Fluid Dynamics (CFD) computer programs. This study investigates turbulent natural convection of a fluid with a Prandtl number of 0.71 in a differentially heated square cavity with adiabatic top and bottom walls. Two different boundary conditions are applied to the side walls; (1) the standard isothermal side wall problem, and (2) the mixed isoflux/isothermal problem, which has a constant heat flux on the heated side wall with an isothermal cold wall on the opposite side. An experimental study is carried out to determine the net convective heat transfer between isothermal hot and cold walls for a range of wall temperature differences in the laminar flow regime. The experiment data is compared with CFD predictions, and they are found to be in reasonable agreement......
