A critical review of predictive models for the onset of significant void in forced-convection subcooled boiling

Abstract

The predictive models for the onset of significant void (OSV) in forced-convection subcooled boiling are reviewed and compared with extensive data. Three anMytical models and seven empirical correlations are considered in this review. These models and correlations are put onto a common basis and are compared, again on a common basis, with • variety of data. The evaluation of their range of validity and applicability under variousoperating conditions are discussed. The results show that the correlations of Sah_-Zuber (1974) seems to be the best model to predict OSV in vertical subcooled boiling flow.
