ABSTRAKT

This paper contains measurements in stratified oil/water flow in a horizontal pipe. In the experiments the oil/water ratio is varied, but the bulk velocity is constant. Laser Doppler Velocimetry (LDV) is used to measure the local axial mean velocities and the axial velocity fluctuations. Local phase fractions are measured with a traversing Gamma Densitometer. The velocity profiles of the two-phase flow are compared to single-phase flow, displaying significant differences. The local phase fraction measured by Gamma Densitometry (GD) give information about the flow regime and the location of the oil/water interface inside the pipe. The stratified oil/water flow is also simulated with the Volume Of Fluid (VOF) model, but the complex flow fields measured by LDV do not appear.
