<p>The thesis begins with a literature review of phase change material (PCM) and heat transfer intensification methods. The challenges of using these methods are discussed, and the potential of adding nanoparticles as one of the heat transfer enhancement methods is explored thoroughly and presented. Also, the potential of implementing thermally enhanced latent heat thermal energy storage (TES) in a ground source heat pump (GSHP) system is presented. A detailed study has been carried out on developing an enhanced numerical approach to investigate the melting performance of nanoPCM (exfoliated graphene nanoplatelets (xGnP)octadecane) filled in a vertical cylindrical enclosure at different weight concentrations. The results showed that by adding 0.5wt% of xGnP in the base PCM (octadecane), the melting rate decreases by 9.7% and the heat storage rate increases by 12.6%.</p>

“…Therefore, it is important to determine how different factors and their combinations affect the phase transition process and predict the relationship between the operating factors (independent parameters) and responses (dependent parameters). For example, Yu et al [12] conducted a study to determine the influence of PCM thermophysical properties on the charging process under steady and fluctuating heat source conditions and obtained a heat storage capacity and charging rate regression model. Yu et al [13] performed optimization of the geometry of a shell-and-tube latent heat storage (LHS) unit with a tree-like fin using the response surface method (RSM).…”

The study presents the experimental and analytical investigation, which was carried out to evaluate the charging/discharging performance of phase change material (PCM) in the thermal energy storage (TES) unit. The experiments performed under different operating modes of the heat storage system, changing the inlet temperature and the mass flow rate of the heat transfer fluid (HTF). The calculated amount of thermal energy based on the partial enthalpy distribution provided by the manufacturer’s datasheet compared to that obtained from the experiments. Based on the experimental results, a three-dimensional response surfaces formed and a regression models obtained, which allow predicting the PCM charging and discharging performance.
