Numerical Investigation of the PCM Type and Position Influence on the Melting Process in a Concrete Wall

The main aim of the paper is to investigate the influence of PCM type on the transition melting interface where the PCM loses its ability to completely melt within a concrete wall, and to locate the thermophysical properties of phase change material that has a direct effect on its position. In this work a comparative analysis was used on different type of PCM through a two-dimensional mathematical model for simulating and analyzing the melting and solidification of PCM in order to enhance and optimize its latent heat storage. The thermal performance and influence are evaluated using different PCM position for different PCM type with different thermophysical properties. The governing equation for energy transport were developed by the enthalpy method and discretized with volume control scheme which were solved iteratively using TDMA algorithm.
