Control volume finite element numerical simulation of mixed convection in an air-cooled cavity

This paper presents a numerical study of transient mixed convection of lami nar flows in an air-cooled cavity in which a fluid is injected at a tempera ture lower than the initial temperature of the cavity. A control volume fin ite element method (CVFEM) using triangular elements is employed to discret ize the governing equations. The performance of Be numerical algorithm is f irst tested. in order to investigate the quality of the ventilation and coo ling, the dynamic and thermal fields are numerically determined for a large range of Reynolds and Richardson numbers and for different inlet-outlet lo cations. Cooling efficiency is examined at transient and at steady regimes.
