Abstract

Abstract: The heat transfer of nozzles on the roof of LNG cryogenic tank is studied according to the basic theories of heat transfer, including the analysis of the heat transfer process, the simulation of nozzle temperature field using ANSYS and the sensitivity analysis and optimization of nozzle size and structure parameters. As it turns out, the primary factor affecting the temperature at the joint between thermal sleeve and tank roof plate is the length of the thermal sleeve; which, together with the external insulation thickness and the insulation length of the thermal sleeve, are the major factors affecting the external surface temperature of the thermal sleeve. The analyzing methods and results can serve as a theoretical basis for the structure design of similar nozzles on the roof of LNG cryogenic tank.

Key words: cryogenic tank, heat transfer, sensitivity analysis, optimum design
