Flashing flow in the rotating curved channels with variable cross-section of a two-phase flow turbine

The rotating flash flow has rarely been studied, although its characteristics affect significantly the performance of two-phase turbine. In this paper, through analyzing flashing obtained by CFD methods, which is validated with experimental data, relationships average parameters under various rotational speeds were studied theoretically and numerically using equations established on Frenet coordinate system. ratio mass rate was formalized found to be dependent speed thermophysical properties. generation development vapour revealed correlated geometry channel. secondary in channel discussed rotate opposite directions upstream/downstream throat. induced near throat had effect homogenizing normal direction cross-section. analysis could further applied analogy between single-phase flow.
