However, the presence of certain phenomena such as convection and supercooling may affect the fusion times and, consequently, the design of PCMs. Supercooling can have a noteworthy impact on the system performance. Moreover, convection alters the shape of the phase-front and should also be taken into account. Thereby, we propose here a thermal lattice Boltzmann model (TLBM) to simulate the phase-change problem with convection and supercooling. The numerical findings show that convection and supercooling phenomena are successfully taken into consideration. In addition, where appropriate, supercooling results exhibit a delay for the propagation of the solid-liquid interface. This proves that consideration of such a phenomenon in numerical modelling remains paramount for better design of PCM design.Lire moins >
