Heat transfer analysis of fin & tube heat exchanger is majorly considered for cooling using convection process in most of the industrial process. In order to understand the temperature distribution and to minimize the heat losses, heat transfer analysis help us to understand the temperature profiles of fin & tube sections. An aluminum section of fin & tube heat exchanger with axi-symmetric model of 90 deg section is considered. The tube carries a contained hot fluid while the exterior surfaces
