The effect of the fluid properties on the wave velocity and wave frequency of gas-liquid annular two-phase flow in a horizontal pipe

摘要

The effects of fluid properties on the wave velocity and frequency of gas-liquid annular two-phase flow were investigated in 26 and 16-mm inner pipe diameters. The liquid viscosity was varied from 1.02 to 6.57 mPa s using water and glycerol solution and the surface tension was varied from 34.0 to 71.7 mN/m using water and butanol solution. The range of superficial liquid and gas velocities were set to 0.05-0.2 m/s and 12-40 m/s, respectively.
