In recent years, shell and tube latent heat thermal energy storage system (LHTESS) with phase changing materials (PCM) are used to store energy. The major drawback of latent heat storage system is due to low thermal conductivity of PCM the heat transfer is low. In this study, a 2-dimensional horizontal shell and tube latent heat storage system is considered, the rotation is implemented to accelerate charging process of the system. ANSYS FLUENT 2022 R2 software is used for the simulation and calculation. Paraffin wax (n-octadecane) and water are used as PCM and hot fluid (HTF) respectively. The simulation and calculation are carried out for 0.5 rpm, 1 rpm and 1.5 rpm and these results are compared with stationary counterpart. The result show that rotation accelerate melting process. The percentage thermal enhancement between rotation and stand stand still for 0.5 rpm, 1 rpm and 1.5 rpm are 8%, 18.61% and 25.38% respectively.
