In this study, we numerically investigated the influence of the baffle length and emissivity of the walls on heat transfer in a mixed convection coupled with radiation in a rectangular cavity ventilated. The baffle length is used Lb = 0.3, 0.5 and 0.7. The cavity walls are gray. The left vertical wall is heated to a constant heat flux and the other walls are adiabatic. The finite volume method is used to solve the governing equations. At the input of the cavity whose opening height w =H/10, the fluid velocity is determined from the number of Reynolds Re between 50 and 500. The Grashof number Gris fixed to 104 and the Prandtl number Pr is kept constant 0.71. The results obtained in this study show that the heat transfer enhancement depends on the increase in emissivity; However, the increase in total Nusselt number NuT depends on the increase of the baffle length.

“…Rao et al numerically suggested a correlation for maximum temperature in the walls of a vertical channel mounted with heat generating obstacles with effect of radiation under laminar, incompressible mixed flow condition [16]. Londhe et al carried out a numerical study under conjugate mixed convection flow of air in a vertical channel mounted with discretely heated heat sources by considering the effects of radiation [17]. It is concluded that the radiation effects cannot be neglected in all the regimes of mixed convection.…”

“…It is clear from the above illustrated literature that, the investigation carried out were focused on the optimal spacing problems related to the arrangements of heat generating sources placed in a channel (Vertical/horizontal) or stack of heated plates subjected to forced, free and mixed convection flow regime with or without considering the conjugate condition [5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Numerical studies reported by the Ramis et al were associated with single heat generating plate subjected to forced convection flow of coolant under conjugate, laminar, incompressible flow condition [3,4].…”

The objective of present investigation is twofold, one to determine the effect of operational parameter on maximum temperature (Hot spots temperature) in heat generating (uniform and non-uniform) vertical parallel plates and two is to find out the position of maximum temperature (hot spots location) when plates are placed apart at optimum spacing (Bopt). A conjugate two dimensional laminar forced convection analysis is carried out in which the equations regulating the heat and fluid flow are solved by using finite difference numerical technique and the obtained algebraic equations are solved by using Thomas algorithm. The parameters viz Reynolds Number (ReH), Conduction-Convection parameter (Ncc), Heat generation parameter (Qt), and Prandtl Number (Pr), Spacing between the plates (B) were considered for present study, while the aspect ratio (Ar) of the plate is kept constant. The major outcome of present study says that the location of hot spot is mainly affected by ReH and mode of heat generation (uniform and non-uniform). It is also found that the spacing between the plates (B), ReH, Pr and Ncc play a major role in reducing the hotspots temperature.
