abstract

  • An enthalpy transforming scheme is proposed to convert the energy equation into a non-linear equation with the enthalpy, E, being the single dependent variable. The existing control-volume finitedifference approach is modified so it can be applied to the numerical performance of Stefan problems. The model is tested by applying it to a three-dimensional freezing problem. The numerical results are in agreement with those existing in the literature. The model and its algorithm are further applied to a threedimensional moving heat source problem showing that the methodology is capable of handling complicated phase-change problems with fixed grids. © 1989.
