| 摘 要： | 研究了由AP1000核电厂一回路热管段和ADS-4管道组成的大尺寸支管T型管液体夹带的实验和理论模型,主要包括起始夹带和稳态夹带模型的研究。通过实验和理论分析,建立了与实验数据符合良好的起始夹带模型和稳态夹带模型。通过分析实验段入口长度对夹带的影响,确定了合适的入口段长度。不同液体流量下的研究表明,ADS-4管道中,液体流量对起始夹带和稳态夹带的影响可忽略。

| Abstract: | An experimental and theoretical study was performed for establishing the model of liquid entrainment at T-junction consisting of hot leg for AP1000 nuclear power plant and ADS-4 pipe, including onset entrainment and stable entrainment models. Based on the experimental and theoretical analyses, onset entrainment model and steady-state entrainment model were established, which accord with experiment data well. The influence of entrance length on entrainment was discussed to determine the entrance length of the test section. The effect of liquid flow on onset entrainment and stable entrainment was analyzed, and the experiment results show that the effect of liquid flow on entrainment through ADS-4 pipe can be neglected. |
