摘要: Abstract The two-phase frictional pressure drop was measured in a 0.15 m internal diameter bubble column operated continuous co-current manner. fractional gas hold-up using the gamma-ray absorption technique and modified differential manometry. superficial liquid velocities were varied ranges 0.127–0.451 s −1 0.047–0.236 respectively. effects of viscosity, non-Newtonian behaviour, presence electrolyte investigated. A coherent model developed to predict homogeneous (bubbly flow) heterogeneous (churn-turbulent) regimes. For this purpose, knowledge phase flow pattern used. comparison between predictions experimental observations is presented. On basis drop, criterion transition from regime. favourable shown observations.
