Convective Heat Transfer Analysis of Longitudinal Fins on Horizontal Hollow Cylinder

Abstract
The thermal system under consideration is a horizontal hollow cylinderwith longitudinal fins of constant length, varying thickness and constant temperature condition at the inner wall. The convective heat transfer coefficient taken on the outersurface of the system isvarying. The Heat flux and efficiency of the system is analytically validated and then ANSYS FLUENT is used for numerically solving the problem. A total number of 135 cases were solved. The temperature contour of the system along the length is also studied. The variation of heat flux and efficiency is shown with the help of plots with the optimum result.
