中文摘要:

      本文提出了一种推测圆管流动中的气液物质组分的理论新方法。通过建立圆管中充分发展管段的气液两相分层流对流换热模型，采用L-M方法对气相和液相流体的热参数分别进行非线性模拟和反算，利用反演的热参数求解物质分别在气相和液相的组分，最后根据两相流动控制方程，推求出圆管中两相流体存在浓度滑移时的总组分，为以后封闭系统中的物质组分实时监测提供理论基础。

英文摘要:

      This paper proposes a new theory of calculating gas and liquid components in the pipe flow. One dimensional unsteady heat conduction inverse problem model for nonlinear simulation of the convective heat transfer equation thermal parameters is proposes in this paper by means of L - M method in the gas phase and liquid phase fluid respectively and, using the inversion of the thermal parameters to solve the matter in the composition of gas phase and liquid phase respectively, and then ascertain total component when the fluid exits concentration slip according to the two-phase flow control equations，which could provide theoretical and reasonable basis for components real-time monitoring in the closed system.
