对双螺杆油气多相流混输泵的基元容积及其回流通道进行了详细地几何解析 ,并建立了回流通道的两相回流模型 ,对基元容积间的两相回流进行了动态模拟。
The geometry of the elemental volume and its return channel of the twin screw oil-gas multiphase flow hybrid pump was analyzed in detail. The two-phase return flow model of the return channel was established and the two-phase return flow between the elemental volumes was dynamically simulated.
