Abstract

Numerical and experimental study is carried out for the steady laminar natural convection of air in a vertical annulus with constant heat flux heated inner wall and an isothermally cooled outer wall. The primary objective for the numerical study is to show the effect of the radius ratio of the vertical annulus on the fluid flow structure and heat transfer. The momentum and energy equations are used for the numerical model and are solved numerical by the finite difference technique. Results are generated for flow in an annulus with aspect ratio A=2, Rayleigh number 10
