摘要
双流体模型是最近提出的一种计算两相流的方法,在分别求解两相各自的控制方程时考虑了相间的动量、能量和质量输运。本文使用这一模型并借助大型计算机程序(凤凰程序)对蒸发管内气液两相流进行了计算,得到的结果物理上合理。
The two-fluid model is a new method proposed recently to calculate the two-phase flow problem. In solving the governing equations of each phase, it also considers the momentum, energe and mass transmission between the two phases. The objective of this work is by using this model to calculate the vapour-liquid flow through a heated pipe. The result seems physically reasonable. This shows that the two-fluid model is a potiential way for analysing two-phase flow, but some of its assumptions have not yet been verified, and need improving in accordance with experiments.
