A computational study has been performed to make a computational analysis of natural convection and entropy generation in a sharp edged finned cavity. Three dimensional analysis has been done by solving governing equations with a written computational code in Fortran. The study is performed for fin inclination angles from -60° to 60°, Ra = 105, Pr = 0.7, Rc (conductivities ratio) changes from 0.01 to 100 and irreversibility coefficient is taken as φ=10-5. It is observed that higher values of thermal conductivity ratio (Rc ≥ 1) do not affect entropy generation due to heat transfer and Bejan number.
