Numerical study the effect of the ratio of partly filled corrugated cavity with a porous material to the total height cavity of convection heat transfers

The goal of this investigation is to determine how a fluid portion’s aspect ratio A1 relative to cavity height affects natural convection in a partially porous container. In the porous part, a constant heat source is introduced at bottom (300,500,700,900.1100 W/m2), top is exposed to environment and...

Description
Summary:The goal of this investigation is to determine how a fluid portion’s aspect ratio A1 relative to cavity height affects natural convection in a partially porous container. In the porous part, a constant heat source is introduced at bottom (300,500,700,900.1100 W/m2), top is exposed to environment and other walls kept at a constant temperature. The energy equation and the Darcy-Brinkman extension are used to modify the Navier-Stokes equations, which explain the equations for thermal transfer and hydrodynamic flow. The results are represented by an isotherm’s distribution (temperature distribution), effect of modified Rayleigh number and velocity streamlines.
