Abstract
The characteristics of shock waves and expansion waves of two-phase flow, which has essentially low sound speed, should be elucidated to aid in optimizing the design of ejector for refrigeration systems. At the mixing section of the two-phase ejector, the supersonic driving flow mixes with the subsonic suction flow which generates shock waves and expansion waves. This study focuses on the existence of two-phase oblique shock waves based on momentum and temperature relaxation. The oblique shock waves were calculated using two-dimensional CIP method. The analytical results obtained were quite different from the results using one-dimensional supersonic flow. We found out that the characteristics of high speed two-phase flow is largely affected by the momentum and thermal relaxation times.
