Adiabatic Performance Analysis of Cryogenic High Pressure Vessel wound by Flat Metal Strip |
| |
| Abstract: | Cryogenic high-pressure vessel wound by flat metal strip with a liquid nitrogen precooling jacket is a new fashion adiabatic equipment, which consists of inter vessel and outer vessel. The average evaporating ratio is an the important parameter to scale its adiabatic performance. Based on the analysis of its heat transfer process and the effecting factors of temperature difference, this paper provided an engineering method to calculate the evaporating ratio, and had a calculation combined with the example of 10m 3 liquid hydrogen storage. The result showed that the cryogenic vessel wound by flat metal strip has the preferable adiabatic performance and is suitable for cryogenic storage of important medium. |
