竖直空气射流对氦气层侵蚀行为的数值模拟OA北大核心CSCDCSTPCD
Numerical Simulation for Erosion of Helium Stratified Layer Under Effect of Vertical Air Jet
核电厂在严重事故时会有大量氢气释放到安全壳中,为研究氢气在安全壳内的分层、混合、复合等复杂现象,OECD发起了SET H-2项目。在SET H-2框架内,PANDA实验台架上进行的ST1_7_2实验利用氦气替代氢气,来模拟竖直空气射流对氢气层侵蚀的过程。本文使用C FD技术对该实验进行了数值模拟,并分析了浮升力湍流模型以及不同湍流Schmidt数对模拟结果的影响。研究结果表明:数值模拟较好地再现了实验的侵蚀过程,但射流的侵蚀速率小于实验的侵蚀速率…查看全部>>
In the case of a severe accident in nuclear power plant , some amount of hydrogen will be released into the containment . In order to investigate the complex phenomena such as stratification , mixing and recombination of hydrogen , SET H-2 project is initiated by OECD .In the frame of SET H-2 project ,ST1_7_2 experiment conducted on PANDA facility used helium as substitute of hydrogen to simulate the erosion process of a hydrogen stratified layer by a vertic…查看全部>>
