基于可视化夹带实验,本文对由水平主管段和大尺寸支管组成的T型管进行夹带起始和稳态夹带研究,并与 RELAP5中的气相夹带模型进行对比。结果表明：本实验中夹带起始时所出现的漩涡形式与前人的研究结果相似；稳态夹带实验中观察到一种全新的无旋夹带形式；压差与气相夹带基本为线性关系,T型管主管与支管压差越大,气相夹带越小。

The onset entrainment and stable entrainment for T-j unction composed of a large downward-oriented branch and a horizontal main pipe were researched based on visualization experiment.The gas entrainment experiment results were compared with the calculating results from RELAP5 .The experimental results indicate that the forma-tion of vortex at the onset entrainment is similar with the previous research results.A new vortex-free entrainment formation is observed during stable entrainment. The entrainment quantity of gas has linear relation to the pressure difference.The entrain-ment quantity of gas decreases with the increase of pressure difference between the branch and the horizontal main pipe.
