Applying heat-entropy analogies with experimental study of interface tracking in phase change heat transfer

Heat-entropy analogies are applied to problems involving phase change heat transfer with fluid flow. In the experimental studies, entropy is not measu red directly, but temperature and other measurements yield associated entro py results for improved understanding of the phase change processes. The en tropy-based framework is shown to serve an important role in modelling of m omentum phase interactions and thermal recalescence, as well as numerical s tability in the computations. Numerical and experimental results indicate t hat entropy can serve as an effective variable in describing and predicting various interfacial processes during phase change.
