Temperature Field Analysis of LNG Tank under Ultra-Low Temperature Based on Finite Element Method

LNG tank has extremely low operating temperature, hazardous storage medium and large capacity storage space, therefore it is necessary to carry out temperature field analysis for LNG tank under Ultra-low temperature, and the temperature of LNG tank under Ultra-low temperature is simulated based on finite element method. Firstly, the finite element model of temperature field is analyzed. Secondly, the simulation parameters of LNG tank under Ultra-low temperature are given. Finally, the simulation results are carried out, and the temperature field of LNG tank under Ultra-low temperature is obtained.
