Analysis of flow and thermal maps during natural convection within porous triangular configurations subjected to linear heating at inclined walls

Heat and fluid flow trajectories are visualized during natural convection subjected to linear heating of the inclined walls involving two representative inclination angles ((Formula presented.) and (Formula presented.)) for different configurations (configurations 1 − 3) of the porous isosceles triangles. Heat transport to the core and cold section of inclined walls due to linear heating is studied using heatlines via tuning various dimensionless parameters Prm, Dam at fixed Ram. Local heat transfer rates are found by evaluating Nu at the inclined walls. Overall, configurations 2 and 3 are recommended based on larger magnitudes of local heat transfer rates at middle regime of the walls, irrespective of (Formula presented.) and Prm at (Formula presented.).
