In this we will comparing the geometries (cylindrical & rectangular) for different inclination angle with same hydraulic diameter. Natural convection is a heat transport mechanism in which the fluid motion is by naturally means no external source is required, temperature gradient is occurring due to density difference. Forced convection is a heat transport mechanism in which fluid motion is by an externally. It is one of the most important heat transfer mechanism in which maximum amounts of heat energy can be transferred very efficiently. We compare by calculating average heat transfer coefficient and Nusselt number for both geometries, for inclination angle (i.e. 0°, 15°, 30°, 45°, 60°, 75°, 90° ). It is concluded that average Nusselt number, for angles ( 15°, 30°, 60°, 75°, 90°) shows maximum heat transfer rate for cylindrical test section and for angle (00, 450) shows maximum heat transfer rate for square test section and also we found that heat transfer coefficient rate increases with inclination angle in both cases.
