摘要：The numerical simulation of ice melting in water considering temperaturedependent material properties and phase-change effects is proposed in this work. The governing differential equations (continuity, linear momentum and energy) are spatially discretized within the finite element method together with a implicit Euler scheme for the time derivatives. The melting of ice initially at –4.3 ºC and surrounded by water at approximately 15 ºC is particularly studied. The effects of variable properties, the incidence of natural convection and different environmental transfer conditions are analyzed with the aim of computing the temperature evolution at various points of the domain. Moreover, the model is validated by comparing the obtained predictions with experiments carried out in the context of this work.
