For determining the axial distribution of void fraction in subcooled boiling, the heat balance equations of vapor production and liquid heating were used. Solution of these equations required adequate expressions for the vapor generation and condensation rates. The vapor generation rate was expressed as the superheated part of the thermal boundary layer enthalpy, while the condensation rate could be derived as the subcooled part of the thermal boundary layer enthalpy. The resulting quality distribution was converted into the void distribution using the Zuber and Findlay void correlation. The model was checked by comparing measured data available in the open literature with calculated results, and surprisingly good agreement was found.
