Experimental Study of Two-Phase Flow in a Horizontal Circular Channel: Influence of Gas Injection on the Bubble Diameters

摘要

This study aimed to examine experimentally the effects of the injector on two-phase flow characteristics such as local void fraction and bubble diameter for water-air two- phase flow in a horizontal channel having 40 mm inner diameter. During the experiments, flow rate was kept constant at 3 l/s while that for air is taken as 30 and 60 l/min. Measurements were made locally via dual optical probe and the results were presented.
