ULTRASONIC MEASUREMENTS OF FLOW IN TWO-PHASE LIQUID-GAS SYSTEMS.III.FLOW AREA,SUPERFICIAL VELOCITY AND VOLUME SHARE OF THE GAS PHASE

摘要

The paper presents the method for determination of the gas phase flow area with the accuracy of delta x equal to 0.4 mm.Based on the analysis of distribution curves of the moving bubbles the surface flow rate has been determined,referred to the actual flow area,and volume share of the gas phase for a given flow height.In majority papers reporting on the studies of the area of existence of gas phase in two-phase flows,the authors based on the analysis of the flow pictures obtained from theoretical models of movement of gas bubbles/stream in a column filled with water[1-15].
