“…Basak et al [9] investigated natural convection inside a triangular enclosure with linear heating/cooling on the inclined surfaces. Natural convection in an attic space filled with porous media has also been conducted by a number of researchers [12,13,14,15]. In this study, we consider a triangular enclosure filled with porous media and heat generating fluid with non-uniform temperature conditions on one of the sloping walls.…”

Unsteady natural convection inside a triangular cavity is studied. The cavity is filled with a saturated porous medium has a nonisothermal left inclined wall while the bottom surface is isothermally heated and the right inclined surface is isothermally cooled. Internal heat generation is also considered, which is dependent on the fluid temperature. The governing equations are solved numerically by the finite volume method. The Prandtl number of the fluid is chosen to be 0.7 (air) whereas the aspect ratio and the Rayleigh number are 0.5 and 10 5 , respectively. The effect of heat generation on the fluid flow and heat transfer is presented in terms of streamlines and isotherms. The rate of heat transfer through the three surfaces of the enclosure is also presented.

The problem of double-diffusive convection in inclined triangular porous enclosures with sinusoidal variation of boundary conditions in the presence of heat source or sink was discussed numerically. The dimensionless governing equations of the problem were solved numerically by using finite difference method. The effects of governing parameters, namely, the dimensionless time parameter, various values of the inclination angle, Darcy number, the heat generation/absorption parameter, the buoyancy parameter and the amplitude wave length ratio on the streamlines, temperature and concentration contours as well as the velocity component in the x-direction at the triangle mid-section, the average Nusselt and Sherwood numbers at the bottom wall of the triangle for various values of aspect ratio were considered. The present results are validated by favorable comparisons with previously published results. All the results of the problem were presented in graphical and tabular forms and discussed.

“…They found that the heat transfer rate is larger for square cavity compared to trapezoidal cavity. Varol et al [14] studied the effect of aspect ratio of a porous triangular cavity on natural convection flow and heat transfer and found that the heat transfer decreases on increasing the aspect ratio. Anandalakshmi et al [15] studied convective flow in a rightangle triangular cavity with adiabatic bottom wall and various thermal boundary conditions on the side walls.…”
