BRITO, R.; MENON, G.J.  y  DIAS, J.B.. Mixed Convection in Rectangular Cavities with Inlet and Outlet of Fluid. Inf. tecnol. [online]. 2004, vol.15, n.4, pp. 56-64. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642004000400008.

This study determines the velocity and temperature fields as well as the average Nusselt number (Nu_h) on a vertical isothermic wall inside a partially open rectangular cavity. The conservation equations are solved using a finite element method. The numerical results show that the higher the Reynolds and Grashof numbers, the greater is the heat transfer on the isothermal hot wall. For low Reynolds numbers (Re), the Nusselt numbers (Nu_h) obtained in the present work were close to those found for natural convection in a rectangular closed cavity. From the thermal and geometric parameters studied, it is concluded that it is possible to improve the efficiency of cooling of the interior of a partially open rectangular cavity
