Fully Developed Forced Convection of Three Fluids with Variable Therm o physical Properties Flowing through a Porous Medium Channel Heated Asymmetrically with Large Temperature Differences
要約
The steady laminar flow in a fluid-saturated porous medium channel bounded by two parallel plates with constant but unequal temperatures is studied. For the porous medium the Brinkman-Darcy-Forchheimer model is used. The investigation concerns engine oil, water, and air, taking into account the variation of their physical properties with temperature. The results are obtained with the direct numerical solution of the governing equations and cover large temperature differences. It is found that dynamic viscosity and, in some cases, density and thermal conductivity play an important role in the results, which depart significantly from those of a fluid with constant properties when the temperature difference between the plates is large.
