Abstract
This article is aimed to study the thermal energy transport phenomenon caused by heating the porous cavity at left vertical wall as well as an internal heating by a strip of varying length near the cooling surface. The internal heating strip that varies in length is kept at x = 3L/4 of the cavity where L is the overall cavity length. Finite element method is at the core of solution techniques which is employed along with triangular shaped elements. The solution is arrived by following an iterative method that depends on satisfying the equations to a predetermined error level. It is ensured that the results are accurate enough to predict the phenomenon under study. The main aim of the study is to understand what happens when the heating element is placed towards the right vertical surface. The results are described for physical and geometrical parameters of the problem being considered.
