INFLUENCE OF PORE DENSITY ON MELTING OF PHASE CHANGE MATERIALS IN METAL FOAMS——Numerical Simulation with Lattice Boltzmann Method
Based on local thermal non-equilibrium between the metal matrix and phase change materials, the Lattice Boltzmann model was proposed to characterize the melting processes of phase change materials in metal foams. The melting front locations as the function of time simulated by Lattice-Boltzmann model agree well with the results obtained in the other literature. Then, the effects of pore density on the melting processes of phase change materials were investigated. The increase in the pore density not only yield the increasing conduction heat transfer but also results in the decreasing convection heat transfer, thus and may lead to the enhancement or the reduction or limited effect on the total heat transfer ultimately depending on the Rayleigh number.
