摘要
Flow structures in vertical upward two-phase flow in a concentric narrow annular channel have been studied. A map of flow patterns has been drawn. The frictional loss has been measured for the two-phase flow over a wide range of superficial liquid and gas velocities. A mathematical model predicting frictional loss has been developed.
