Résumé

This study deals with a visual observation of two-phase flow of carbon dioxide in a horizontal micro-fin tube. A series of experiments were carried out at 3, 4 and 5 MPa in pressure with varying the mass velocity from 300 to 540 kg/m2.s. The series of visual observation were classified into three basic flow patterns namely, wavy flow, slug flow and annular flow. These flow patterns were plotted on a diagram with the relationship between vapour quality and mass velocity. The flow patterns were strongly influenced by vapour quality and mass velocity. The pressure condition, however, made little impact on the transition of the flow pattern due to the slight change of density ratio of liquid to vapour in comparison to that of traditional refrigerants under the same experimental condition.
