描述了两个典型的液化天然气涡旋事故,分析了分层和涡旋现象形成的机理,介绍了国内外提出的双向对流扩散模型、Bates-Morrison模型和四阶段模型等重要理论研究工作和实验成果,并提出了进一步深入研究的方向。
Two typical LNG vortices are described, and the mechanism of delamination and vortex formation is analyzed. Some important theoretical research work and experiments such as bidirectional convection diffusion model, Bates-Morrison model and four-stage model are introduced Results, and put forward the direction of further research.
