Abstract

The cooling characteristics of the melt have important influence on the process of IVR in a severe accident.An enthalpy formulation based on fixed grid methodology was developed for the numerical solution of convection-diffusion controlled mushy zone phase-change solidification of the melt.The process of the solidification was simulated by solving the N-S equations and the enthalpy formulation equation using the SIMPLE algorithm.The phase-change model could simulate the solidification and mushy zone well,and it was verified by the use of analytical solutions and benchmark problems.
