Numerical Simulation Study of LNG Storage Tank Temperature Field Value Based on COMSOL
The temperature field layout inside LNG storage tank has a significant impact on the structure and performance of the tank.Taking a large LNG storage tank in China as the research object,combined with the structure and material composition of LNG storage tanks,a temperature field model for the top,wall,and bottom of LNG storage tank is established using COMSOL multi physics field software,and simulation is followed.On the basis,the influence of environmental temperature on the temperature of various parts of LNG storage tanks is studied.The research results indicate that the cold insulation performance of the tank bottom is the worst,the tank wall is most sensitive to environmental temperature.The research results provide guidance for relevant engineering practices and technical support for LNG storage and transportation.
