Investigation on Thermal Distribution and Heat Transfer Rate of Fins with Various Geometries

A steady-state combinative conduction–convection analysis is carried out on a fin made up of different materials and different shapes under suitable boundary conditions. The solutions for temperature distribution and heat transfer rate of the fins are provided for different materials like copper, aluminum, iron, stainless steel, and different geometries such as triangular, rectangular, annular, and circular shapes. From tabular and graphical solutions, it is noted that temperature distribution of copper fin with triangular geometry is high but it is low for stainless steel with circular geometry. Copper with circular fin exhibits more heat transfer rate when compared to others.
