Computation of heat transfer with solid/liquid phase change including free convection
Abstract
A computational model is presented for the prediction of solid/liquid phase change energy transport including the influence of free convection. The computational model considers the velocity components of all nonliquid PCM control volumes to be zero but fully solves the coupled mass-momentum problem within the liquid. The thermal energy model includes the entire domain and employs an enthalpy-like model in addition to recent developments for handling the phase change interface nonlinearity. The predictions are compared with experimental data and with previous predictions for the test problem examined. The present procedure demonstrates both excellent agreement with the experimental data and a significant computational cost reduction from previous procedures.
