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

Abstract

While subcooled boiling at high pressures has been studied extensively, the phenomenon is as yet not characterized sufficiently at low pressures. This paper discusses the application of four methods to predict subcooled-boiling void fraction measured in an experiment aimed at separate-effect measurements of subcooled void condensation and generation. The methods include a simple correlation, and a hierarchy of three models, each of which address void generation and condensation at a different level. of complexity. Comparisons are given between the experimental data, and results from each of the prediction methods
