摘要:
针对热力系统管道内气液两相流动，在漂移通量理论和水力模型基础上，综合考虑管道倾角对空泡份额分布参数C0及漂移速度Vgj的影响，提出了一种迭代求解空泡份额的简化水力模型，该模拟的计算结果与绝热管及均匀加热管内两相流动试验数据相比有很好的吻合度，证明了该模型的可用性，为工程实际应用提供了参考。
Simulation program based on the theory of drift-flux and hydraulic model was finished in consideration of the influence of pipe angle on distribution parameter C0 and drift velocity Vgj within thermodynamic system two-phase flow. A research was carried out using a simplified hydraulic model in which the void fraction was calculated by iteration; according to the computing result of both adiabatic and uniform heated two-phase pipelines, the comparison was given, and the details showed that theoretical analysis was well agreed with experimental results and provided a refer- ence for engineering application.
