... solidification. Modeling solidification/melting of substances with moving phase boundaries—the so-called Stefan problem [ 5 ]—is a topic that has been studied extensively, especially in the context of metallurgical processes [ 6 – 8 ] and phase change processes in energy storage applications [ 9 – 11 ], among...

... for using small time-steps is the fine-scale motion generated by natural convection in both the liquid and the gas. A new model is proposed and demonstrated for efficient prediction of the propagation of the solidification front. In this model, heat transfer due to natural convection is modeled...
