Abstract
In a gas-liquid two-phase flow, forces such as surface tension, momentum force and gravity affect on the interaction among dispersed phases such as droplets and bubbles, as well as gas and liquid continuous phases. Gas-liquid two-phase flow experiments under µg environment have been increasingly carried out in recent years using drop shafts, aircraft, and space stations, to evaluate the influence of these forces affecting on the phenomena. Apart from the evaluation of the forces, many efforts have been made to conduct experiments to determine the flow mechanism under µg environment which makes it possible to control the two-phase flow experiments by means of non-convection, non-sedimentation/non-buoyancy, non-static pressure, and also non-contact floatation-conditions which are hardly achievable under normal-gravity environment. This report outlines examples of research being conducted on a gas-liquid two-phase flow under µg environment using the JAMIC drop shaft.
