Comparison of LBM and FVM for Simulation of Solid-Liquid Phase Change Problem with Natural Convection

Abstract Phase change materials (PCM) are wildly investigated and used in the fields of thermal energy storage control electronics. Numerical simulation is an important method research, development, analysis design PCM based systems. At present, there two main numerical methods for solid-liquid phase transition problems with natural convection: finite volume (FVM) on macroscopic scale continuity equations, lattice Boltzmann (LBM) mesoscopic equation. In this paper, calculation characteristics, speed, efficiency, accuracy compared, classical heat transfer experimental results as benchmark reference. The obtained paper can be valuable reference selection use study problems.
