Abstract

Simulation study on hydrogen venting from liquid hydrogen tank of a certain rocket and diffusion form the safety valve of liquid hydrogen tank turning on to its turning off is carried out. Geometry model of safety valve of liquid hydrogen tank is established. And hydrogen venting process is studied when the pressure in the tank is as high as the limited pressure which is 0.35MPa. Hazard zone produced by hydrogen cloud is analyzed and it is valuable for establishing some predicted method to meet possible emergency.
