气泡泵压降模型的分析与优化
Analysis and optimization of bubble pump pressure drop model
摘要
Abstract
Two-phase flow theory was used to establish an one-dimensional and steady state mathematical model of bubble pump pressure drop. Three kinds of homogeneous flow pressure drop models and 15 kinds of split phase flow pressure drop models(three kinds of split phase flow friction pressure drop models with 5 kinds of cross section gas rate models) were selected to simulate,then the experimental data of the bubble pump with saturated water as working fluid were analyzed and compared with the theoretical value. The result showed that simulation accuracy of the Friedel friction pressure drop model combining Zuber section gas rate model is the highest. However,when we use this model to simulate the flow characteristics of the liquid lift of the bubble pump with the change of the heating power,we found that the theoretical value and the experimental value agree well only within a certain range of heating power. Therefore,sectional optimization on bubble pump model was put forward. We found that the simulation accuracy of M-S split phase flow model combined with Tom variable density section gas rate model is the highest under the working condition of low heating power. The Dukler homogeneous flow model of the friction pressure drop is the best model under the higher heating power working condition. Therefore,the method of optimizing the theoretical model of bubble pump by subsection has high credibility.关键词
