Two Phase Pressure Drop Characteristics in Rectangular Channel With Low Aspect Ratio

    Graphical Abstract
    • Abstract
  • The study on two phase pressure drop in rectangular channel with low aspect ratio (0.05) was carried on using water. The state-of-art correlations failed to satisfactorily predict the experimental data. The dimensionless Nconf can account for the maximum size of the bubble confined in small channel during flow boiling process. The data were used to develop a new correlation based on Lockhart-Martinelli method with Nconf. The correlation is tested against the experimental data, and the relative deviation is in ±15%.
