Corner adiabatic structure design is crucial for the adiabatic structure design of large-scale LNG storage tank. Regarding the corner adiabatic structure as a 2-dimensional problem,ANSYS software is used to analyze the distribution law of its temperature field and heat flux density. Results show that the heat is mainly transmitted to tank through the concrete ring beam and the joint between tank bottom and tank wall. Therefore,to ensure the continuity of corner adiabatic structure is of great importance. At...
