Keywords:
Phase Change Material (PCM), thermal storage, transient, arrangement tubesAbstract
This paper is to present a simple and efficient numerical technique for solving transient
multidimensional heat transfer problem of melting processes and comparison to an
experiment result. The proposed technique comprises an enthalpy-based method for
solving the problems by a finite difference scheme, lump system behavior being assumed
for each node. The multi-dimensional transient heat transfer characteristics in term of
temperatu re distribution history, the temporal storage heat and moving rate ofsolid-liquid
interface in a multi-component phases change material (PCM) heated by the tube array
under inline and staggered arrangement that have been studied numerically. Finite
difference scheme for both time and space variable has been applied to solve the
governing differential equation f or obtained algebraic equation in explicit forms. The
results are presented and discussed in this paper.
