| 摘 要： | 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。 |
| 关 键 词： | 大支管 竖直向下支管 气相夹带 可视化 |

| Abstract: | The onset entrainment and stable entrainment for T-junction 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 formation 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 entrainment quantity of gas decreases with the increase of pressure difference between the branch and the horizontal main pipe. |
| Keywords: | large branch downward-oriented branch gas entrainment visualization |
