dc.description.abstractIn order to improve the melting performance of phase change materials (PCM) in latent heat thermal energy storage unit (LHTES), the Angled rectangular with U-shaped tip fin design is proposed in this work. A two-dimensional numerical model based on enthalpy porosity method and Boussinesq approximation were used to model PCMs phase change transformation and the Buoyancy effect. The melting behavior of PCM is investigated by melt front evolution, temperature variation, effect of natural convection and variation of Stefan and Fourier number respectively. The results conclude that Angled rectangular U-shaped tip fin LHTES design is best suitable to enhances melting performance of PCM. The melting time decreases by 80.60 %, 74.42 % and 79.69 % as compared to Bare pipe for Angled rectangular with U-shped tip fin for PCMs Lauric acid, Paraffin wax and Capric acid respectively. The solidification time also decreases by a factor these PCMs. The melting time also decrease by a factor of 71.13 % due to rotation effect of whole domain for Angled rectangular with U-shaped tip fin latent heat thermal energy storage system.en_US
