| Abstract: | Experimental and simulation were studied by using liquid nitrogen as a medium. The changing laws of the medium＇ s pressure and evaporation rate were obtained at different filling rates. The relationship between pressure rise rate and evaporation rate was established. It is proved that the pressure rise rate can be regarded as the evaluation index of thermal insulation performance for cryogenic vessel |
