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

Abstract Heat–entropy analogies are applied to problems involving phase change heat transfer with fluid flow. In the experimental studies, entropy is not measured directly, but temperature and other measurements yield associated entropy results for improved understanding of the phase change processes. The entropy-based framework is shown to serve an important role in modelling of momentum phase interactions and thermal recalescence, as well as numerical stability in the computations. Numerical and experimental results indicate that entropy can serve as an effective variable in describing and predicting various interfacial processes during phase change.
