AB - 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 nonparallel 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..
