液氮垂直入射潜水过程流动与传热特性研究
Study on flow and mass transfer characteristic for cryogenic liquid diving into water
摘要
Abstract
For the diving process ,imcompressiable Navier‐Stokes equations ,together with phase field equation ,were used to track the interface and flow characteristic which took into account buoyancy and evaporation of cryogenic liquid in water .The mathematical models were combined to predict the penetration depth and evaporation rate of cryogenic liquid in water .Numerical studies have been taken under the conditions of various of initial velocities and initial diameters of liquid nitrogen with these models .The results show that the diameters and the velocities have a great influence on penetration depth ,cryogenic shape and evaporation rate .For the relatively small diameter ,all liquid nitrogen e‐vaporates in water and only vapor comes out of water .For the relatively large diameter ,not all liquid nitrogen evaporates in water and some cryogenic liquid may come out of water .关键词
