Heat transfer in a closed cavity ventilated inside

Benseghir Omar

In this work, we have a tendency to bestowed a numerical study of the development of warmth transfer through the laminal, incompressible and steady mixed convection in an exceedingly closed sq. cavity with the left vertical wall of the cavity is subjected to a high temperature, whereas the proper wall is taken into account to be cold. The horizontal walls square measure assumed adiabatic. The governing equations were discretized by finite volume methodology on a staggered mesh and therefore the easier algorithmic rule was used for the treatment of velocitypressure coupling. The numerical simulations were performed for a good vary of Reynolds numbers one, 10, 100, and a thousand numbers square measure adequate to zero.01,0.1 Richardson, 0.5,1 and 10. The analysis of the results shows a flow bicellular (two cells), one is formed by the speed of the fan placed within the inner cavity, one on the left is thanks to the distinction between the temperatures right wall and therefore the left wall. information of the intensity of every of those cells allowed US to induce an explicit result. and therefore, the values obtained from every of Nuselt convection which permit to graspthe speed of warmth transfer within the cavity.
