Developments in the research of air-water two-phase flows in turbomachinery.

Abstract

Engineering problems associated with two phase flows in turbomachinery have recently become increasingly important in relation to the safety analysis of nuclear reactors or the use of low quality energy resources. The problem is caused by the multiform flow patterns as well as the variety of its applications. However, the mechanics in two phase machines may involve similar phenomena. Developments on the research of air/water mixtures in turbomachinery are briefly reviewed, and the mechanics of two phase flows in rotating flow fields and the prediction methods of the performance of turbomachinery based on some analytical models are discussed.
