Résumé

In order to understand flow configurations and distribution behaviour of gas and liquid two-phase flow in distributors, a basic experiment has been carried out for a two-path distributor by using air and water two-phase flow as working fluids. The two-path distributor was arranged so that one of the paths was downward and another was upward. Both the branches are parallel with each other and they have the same direction as the main channel. The inclination angle of the distributor was changed as horizontal, 30º and 60º. A fully developed air-water two-phase flow enters the main channel and is separated into the branches. The flow is upward when the distributor is inclined. Flow patterns in the main channel were stratified, slug, and annular according to the flow rates of air and water. Flow configurations during the separation were observed by a high-speed camera and effects of gravity and entrance flow pattern were investigated.
