    • Abstract
  • The drift-flux model, as its simplicity, has been widely used in the thermal-hydraulic and accidents analysis, especially in the calculation of void fraction. In view of different-channels and flow regimes, researchers have developed some correlations based on the drift-flux model, five of which were evaluated against the experimental results. The Hibiki-Ishii model for conventional channel is the best with average relative error of 14.1%. Combined with the investigation of bubble motion, it is found that the value of distribution parameter is less than one when 〈Jg〉β<0.027, and a more accurate correlation was proposed.
