推导了双流体模型及其控制方程，在自行搭建的旋转平台上进行了重力作用下水平管内空气-水两相流的实验研究，采集了空气-水两相流的流量、压降和含气率等数据，结果表明，加速度对管内空气-水两相流的特性影响很大，尤其是流量，研究结果有助于将两相流的研究领域扩展到重力条件下，为从理论和数值上研究两相流的流动和传热特性奠定了基础。
The two fluid model and its governing equations were induced in this paper.The experiment of air-water two-phase flow under high gravity was conducted on a self built rotational platform.The flow rate,pressure drop and void fraction of air-water flowing in horizontal pipe were collected.The results revealed that the acceleration dramatically influences the characteristic of air-water two-phase flow in pipes,especially the flow rate,pressure and pressure drop.The results can help the research field of two-phase flow to be spread to high gravity condition and set a primary base for investigating the flow and heat transfer characteristics of the two-phase flow theoretically and numerically.
