Numerical Investigation Of Melting And Energy Storage Of Phase Change Material Within A Square Enclosure
Authors : Chebli Fatiha . Mechighel Farid .
Abstract
The investigation centers on the phase change processes integral to latent heat thermal energy storage (LHTES) units. These processes hold significant importance due to their capacity to store excess energy generated by both renewable and conventional power plants. The focus of the study lies in the intricate solid-liquid phase transitions, which are highly sensitive to alterations in thermal boundary conditions. In this specific study, a numerical simulation was carried out to analyze the behavior of kerosene, as a phase-change material, during the melting process inside a square cavity heated from one side and insulated from the other sides. The simulation was carried out using COMSOL Multiphysics software. The results of the study indicate that, initially, thermal conduction plays a dominant role in the melting process, while natural convection develops as melting progresses
