COMPARATIVE ANALYSIS OF HEAT TRANSFER THROUGH TRIANGULAR FIN USING NUMERICAL TECHNIQUES AND ANSYS

Abstract

The current project work problem has been proposed and its purpose is to investigate the detailed parameters of the conjugate convection of the surface radiation of a typical non-uniform fin, triangular fin. The equation of control of the temperature distribution along the fins is obtained by appropriate conduction, energy balance between convection and radiant heat. The resulting nonlinear differential equations are converted to algebraic form by appropriate finite difference formulas. Solving the algebraic equations obtained using the Gauss-Seidel iterative solver. Computer code in C++ is specifically designed to solve this problem. Grid sensitivity analysis has been performed to achieve the best grid scale. In the above exercises, unequally spaced and equally spaced grids were tried. Discussed in detail the independent parameters, namely the thermal conductivity of the fin material, the surface emissivity and the effect of the convection heat transfer coefficient on the local fin temperature distribution.
