Abstract

Abstract

An experimental investigation of the air-water two-phase flow in a tube with a12mm×12mm square cross-section is performed under reduced gravity on board IL-76MDK Russian airplane. Three main flow patterns of the gas-liquid two-phase flow under reduced gravity conditions are observed. The flow rates of the air and water phases, the water temperature and the pressure inside the test section are obtained. The flow pattern transitional criteria of the gas-liquid two-phase flow at reduced gravity are also discussed.
