Application of Generation and Condensation Models to Predict Subcooled Boiling Void at Low Pressures

While subcooled boiling at high pressures has been studied extensively, the phenomenon is, as yet, not sufficiently characterized at low pressures. The application of four methods to predict subcooled boiling void fraction measured in an experiment aimed at separateeffect measurements of subcooled void condensation and generation is discussed. The methods include a simple correlation and a hierarchy of three models, each of which addresses void …
