AB - The aim of the study is to analyze the effect of two different thermal  boundary conditions on natural convection in a porous triangular enclosure.  Sinusoidal and linearly varying temperature profiles on the left wall are  considered. The top wall of the enclosure is kept to be adiabatic. The Darcy  model is adopted in this study and the governing equations are solved using  the finite difference method for various values of inclination angle and  Darcy-Rayleigh number. The results are presented in the form of streamlines,  isotherms and Nusselt numbers. The heat transfer rates are calculated and  compared between two thermal boundary conditions. The heat transfer is more  enhanced in the case of sinusoidal wall temperature than linearly varying  wall temperature.
