Green’s function solution for transient heat conduction in annular fin during solidification of phase change material

doi:10.1007/s10483-012-1620-x

Abstract

Abstract: The Green’s function method is applied for the transient temperature of an annular fin when a phase change material (PCM) solidifies on it. The solidification of the PCMs takes place in a cylindrical shell storage. The thickness of the solid PCM on the fin varies with time and is obtained by the Megerlin method. The models are found with the Bessel equation to form an analytical solution. Three different kinds of boundary conditions are investigated. The comparison between analytical and numerical solutions is given. The results demonstrate that the significant accuracy is obtained for the temperature distribution for the fin in all cases.

Key words: annular fin, analytical solution, thermoelasticity, chaos, Melnikov function, Poincaré mapping, Green’s function, phase change material (PCM), solidification, thermal energy storage
