Abstract
In the aim to optimize the flow systems, a numerical simulation is carried out to investigate the entropy generation of the aiding mixed convection within two non-parallel vertical plates. The computational procedure is made by solving the laminar, steady and bi-dimensional continuity, momentum, and energy equations with the finite volume method. The plates are symmetrically heated with uniform temperature. The mixed convection flow in the heated vertical channel is studied for two aiding buoyancy conditions (upstream flow between hot plates and downstream flow between cold plates). The calculations are performed for several parameters such as Richardson number or buoyancy parameter (Gr/Re2), Reynolds and Bejan numbers. The results showed that the velocity, temperature and entropy generation profiles within the channel are significantly affected by the later parameters.
