CFD Simulation of Unsteady State Thermal Analysis for Circular Fins

摘要

Analytical solutions to the unsteady heat conduction for a two dimensional cylindrical fin with general boundary conditions obtained by the principle of separation variables. In this research, a computational fluid dynamics (CFD) model of the cylindrical fins is implemented with the help of ANSYS Multiphysics software. The material used for this purpose is steel. In this analysis, the partial differentiation is directly transformed into ordinary differential equations. The results obtained computationally are found in well agreement with the obtained analytically.
