Numerical Analysis of Laminar and Permanent Thermal Natural Convection in a Closed Enclosure with Different Geometries and Conditions

EasyChair Preprint 13727

Abstract

        In this study, we present a numerical analysis of laminar and permanent thermal natural convection in a closer cavity with different geometries and conditions. The resulting system of algebraic equations was then solved using the iterative method with the Gauss-Seidel algorithm and relaxation. The results are presented in the form of isotherms, velocity and stream lines, as well as the Nusselt number as a function of the Rayleigh number, which is the main effective parameter. Our findings indicate that an increase in the Rayleigh number leads to a higher convective heat transfer within the enclosure.

Keyphrases: Closed enclosure, Nusselt number, Rayleigh number, heat transfer
