Effect of the position of the hot source on mixed convection in a rectangular cavity

This work presents a study by numerical simulation of mixed convection in rectangular cavity with sinusoidal temperature imposed on the right vertical wall while other left is kept at cold temperature. The upper and lower walls are thermally insulated, inlet outlet ports respectively located hot to bottom top left. enclosure represents practical system such as an air-cooled electronic device, heat source radiator or component three different positions towards side bottom, center enclosure. All calculations made for range Richardson number from 0 10 Reynolds numbers 50 200. influence number, position amplitude phase deviation Nusselt surface studied. results presented form streamlines isotherms graphs well variation maximum mean under conditions. resolution governing equations obtained using software Multiphysics Comsol based finite element method.
