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

摘要

Heat-entropy analogies are applied to problems involving phase change heat transfer with fluid flow. In the ex- perimental 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 de- scribing and predicting various interfacial processes during phase change.
