Slug Dynamics in a Nearly Horizontal Pipe Using Non-Invasive Measurement Techniques

Abstract

This paper examines the effect of gas and liquid superficial velocities on the dynamics of the slug flow in a nearly horizontal pipeline. Instead of the invasive measurements the experiments were conducted using non-invasive techniques to measure slug frequency and bubble length in the slug flows. A simultaneous PIV-LIF technique was employed to measure the instantaneous velocity of both liquid and gas phases simultaneously using two CCD cameras. Effect of gas superficial velocity on the instantaneous measurements were studied and analyzed.
