NATURAL CONVECTION OF HEAT TRANSFER FOR NANOFLUID IN A PARTIALLY OPEN CAVITY WITH INTERNAL HEAT GENERATION: NON-DARCY EFFECT
RÉSUMÉ
In this work, unsteady laminar convection in a partially open porous cavity filled by Cu-water nanofluid with internal heat generation has been numerically studied using the Darcy−Brinkman−Forchheimer model. The numerical solution of the governing equations are obtained from finite volume method together with power law scheme. The SIMPLE algorithm is used for continuity and momentum equations. Numerical simulations are carried out to find the true effects of Darcy number (10−5 ≤ Da ≤ 10−1), heat generation parameter (0 ≤ Q ≤ 15), solid volume fraction (0% ≤ Φ ≤ 5%), and three different opening positions, while the Marangoni and Rayleigh numbers are fixed at 100 and 104. It is found that the heat transfer rate increases with Da and Φ but decreases with Q. Also, the heat transfer has a significant effect due to the ventilation position.
