Experimental and Numerical Analysis He at Transfer Characteristics of Tubes Arrangement Immersed in a Thermal Energy Storage Material

This paper presents a simple and efficient numerical technique for solving transient multidimensional heat transfer problem of melting processes and then compares the solution to an experimental result. The proposed technique comprises an enthalpy-based method for solving the problem by a finite difference scheme, in which lump system behaviour being assumed for each node. The multi-dimensional transient heat transfer characteristics in terms of temperature distribution history, the temporal heat storage and the movement rate of solid-liquid interface in a multi-component phases change material (PCM) heated by the tube array under inline and staggered arrangement are studied numerically in this paper. The finite difference scheme for both time and space variables is applied to solve the governing differential e quation to obtain the algebraic equation in explicit form. The results are presented and discussed in this paper
