The study considers the prediction of pressure gradients in adiabatic gas-liquid annular two-phase flow in the macro-to-microscale range Twenty-four empirical correlations have been tested against an experimental data bank drawn together in this study containing 3908 points for eight different gas-liquid combinations and 22 different tube diameters, covering microscale and macroscale channels from 0.517 to 31.7 mm in diameter. The correlations of Lombardi, Friedel and Baroczy-Chisholm were… CONTINUE READING
