Numerical Prediction of Convection

Abstract

The governing conservation equations contain seven dimensionless parameters that determine the heat transfer characteristics of the superposed fluid-porous layer system. They are the heater-to-base length ratio, δ, the porous layer-to-total height ratio, η, the overall aspect ratio, A, the Darcy number, Da, the fluid Prandtl number, Pr, the solid-to-fluid conductivity ratio, λ, and the overall Rayleigh number, Ra. To present a thorough parametric analysis of the problem, the effect of each parameter on the flow and temperature fields and on overall heat transfer coefficients is discussed in this chapter.
