How to do phase change problems
WebThis model proceeds as follows. First, estimate the ice-to-water phase change using the transient conduction equation with the latent heat of fusion. Next, compare the first solution to estimates that neglect latent heat. Finally, run additional simulations to evaluate impacts of the temperature interval over which the phase change occurs. Web1 de nov. de 2024 · 1.1 Introduction and Brief History. The Stefan system is a well-known moving-boundary PDE system modelling the thermodynamic liquid-solid phase change phenomena. The associated problem of analyzing and finding the solutions to the Stefan model is referred to as the “Stefan problem .”.
