Velocity Profile of Dispersed Oil-Water Two-Phase Flow in Horizontal Pipe Based on Ultrasonic Doppler

Huan Gao  Chao Tan  Feng Dong  
【摘要】:The overall superficial velocity is a main parameter in oil-water two-phase flow in petroleum industry.The velocity distribution in the pipe is important for measuring it precisely.Pulse-wave ultrasonic Doppler technology has attracted much attention in the field of multiphase flow detection recently,which can obtain the velocity profile of fluid along the measurement line.A pulse Doppler measurement system was used in the experiment that contained four dispersed flow patterns in horizontal pipe.A semi-empirical model relied on the experimental data was built to describe the velocity profile of these flow patterns.
