基于反问题理论的汽液两相上升流流型预测与实验研究
|
摘要
汽液两相流流型的测量在两相流研究中占有重要地位。应用均相流模型建立了圆管内汽液两相上升流压力分布,基于反问题理论反演了汽液两相的物性参数,将反演结果与流型图结合,精确地预测了管内流型,计算结果与实验结果进行了对比,误差小于5%。提出的反演流型的方法,可以推广到水平管、螺旋管,为工程上的汽液两相流设备安全性分析、稳定性分析等提供了一种简单可靠的技术方法。
The measurement of vapor-liquid two-phase flow pattern plays an important role in the study of two-phase flow. The homogeneous equilibrium model was used to establish the pressure distribution of vapor-liquid two-phase flow in circular tube. Based on the inverse problem theory, the physical parameters of the two phases were deduced. Combining the inversion results with the flow pattern map, the flow pattern in the tube was predicted accurately. The calculated results were compared with the experimental results, and the error is less than 5%. The method can be generalized to horizontal tubes and spiral tubes, which provides an effective method for the safety analysis and stability analysis of the equipment of vapor-liquid two-phase flow in engineering.
