摘要：
When the two-phase flow passes an impacting T-junction, the gas-liquid two-phase may split unevenly in the downstream pipelines, and severe mal-splitting has a significant effect on the safety and efficiency of downstream equipment. Up to now, the branching tee has been widely studied, but little attention has been paid on the split characteristics of the impacting tee. Based on the analysis of the experiment, model, and theory experiment, this paper reviews the existing problems of two-phase flow splitting at impacting T-junction, and looks forward to the future research direction. This paper describes the experiments of impacting tee with different angles and the impacting tee with the inclined line. The phenomenological model based on the streamline division method and the mechanism model based on the pipeline pressure drop are summarized. The influence of the direction of the branch pipe, the flow pattern at the entrance of the T-junction, the symmetry of the downstream pipeline, the flow state in the inclined pipes, and the pressure drop in the downstream pipeline on the gas-liquid two-phase flow characteristics are summarized. The future research direction is clarified, the next research work can be carried out to improve the prediction accuracy by improving the gas-liquid two-phase flow split model, and to study the two-phase flow split character at the T-junction by combining the flow state in the downstream pipelines with the momentum balance theory. © 2021, Chemical Industry Press Co., Ltd.
