Description
Summary:In this paper Numerical investigation of natural convection flow in a rectangular porous enclosure with non-linear and inertia effects were considered. The dimensionless non-linear coupled partial differential equations are solved numerically with an appropriate set of boundary conditions using finite difference method. Two vertical sidewalls of the rectangular cavity are maintained at the same temperature and the top and bottom horizontal walls are taken at two different temperatures and the cavity is inclined at γ angle. The numerical results are presented in terms of streamline isotherm and Nusselt number for various parameters such as Rayleigh-Darcy number, Darcy number, aspect ratio, top wall temperature, for different value of γ= 0°, 15°, 45° and 75° and nonlinear coefficient.
