Abstract

•Analytical solution of latent heat storage system consisting of cylindrical container.•The effect of volumetric heat generation on melting and solidification process is investigated.•The phase change is caused by outer convective heat and/or by heat generation in PCM.•The phase change material (PCM) can contains metallic particles of nanometric size.•The developed model is validated by comparing the obtained results with literature.

The aim of the present work is to develop an analytical solution to study volumetric heat generation effects during melting and solidification of nano-enhanced phase change material (PCM), encapsulated in horizontal cylindrical container of thermal energy storage. The mathematical model is based on pure conduction in PCM subject to convective heat transfer on outer surface of cylindrical capsule. The variables separation method and exponential integral function have been used to solve energy equation in both solid and liquid phases on transient regime. The model developed in this study was applied to previously reported experimental results and we found a good fit with our model. A parametric study was conducted to investigate the effects of volumetric heat generation on the phase change process during melting and solidification.
