Abstract
The present work concerns the modeling and numerical simulation of the melting of a phase change material (PCM) in a latent heat storage unit. A mathematical model based on the conservation equations of mass, momentum, and energy has been developed. These equations are then discretized using the finite volume approach and the pressure correction method for the treatment of velocity-pressure coupling. The energy conservation equation of PCM was formulated using the enthalpy method. A series of simulations were carried out on a type of phase change material (Paraffin Wax P116) to study the impact of the mass flow rate and heat transfer fluid (HTF) inlet temperature on the performance of the storage unit. The flow structure and the temperature field are also investigated.
