| 摘 要： | 基于两相流基本理论,采用Fluent建立油气润滑系统水平管路中油气两相流的模型,并分析形成环状流的条件。在此基础上,提出新的供油方式,即在润滑油区域有一微小间隙,使压缩空气可直接穿过润滑油中间的空隙;分析新供油方式下形成环状流的条件。结果表明,新的供油方式下油气形成环状流的效率高,环状流液膜均匀性好;在相同供油量情况下,新供油方式形成环状流需要的入口气相速度低,且气速增大时一般不会形成夹带液滴,能够实现较好的环状流流型。

| Abstract: | According to the basic theory of two phase flows,the model of the two phase flows in the horizontal pipe of the oil-gas lubrication system was established by the Fluent software to analyze the shaping process of the oil-gas annular flow in the oil-gas lubrication system.The condition of shaping the oil-gas annular flow in the system was found,a new oil supply style with a small gap at oil district was put forward,and its condition of shaping the oil-gas annular flow was found.Results show that with the same oil amount,the new oil supply style needs a lower gas velocity in the inlet to shape the annular flow,and the oil drops will not appear in air flow.The new oil supply style has a more efficiency shaping process and a more even of the annular flow than the old one. |
