Numerical Study of Melting/Solidification by a Hybrid Method Couplinga Lattice Boltzmann and a Finite Volumes Approaches

摘要

In this paper, we propose a hybrid method coupling a Lattice Boltzmann Method (LBM)and a Finite Volume Method (FVM), to study melting and solidification problems. The LBM isused to determine the dynamics field while the FVM is applied to discretize the energy equation.This model is validated by comparison to available literature results concerning a square cavityheated without phase change then for the melting of Gallium in an enclosure commonly used asbenchmark test case.
