Parametric study of the dimensionless numbers effects on the thermal behavior of PCM wallboards when it used to store thermal energy in building structures

Thermal energy can be stored as a latent heat in building structures by materials with low phase change temperature called phase change materials (PCM). In this paper, an analytical and mathematical study of the PCM wallboards was done by simulate its thermal behavior, depending on governing heat transfer equations which describe the phase change process of the PCM wallboard.
