In this paper, the flow of liquid LNG in the nozzle is analyzed, and the results are taken as the initial conditions and boundary conditions for LNG spray calculation. On this basis, a numerical simulation model of pure liquid LNG flash boiling spray was created to investigate the development of the spray process. The temperature of LNG, the injection pressure and the ambient pressure are studied by the method of AVL-FIRE software.The results showthat, with the increase of the injection pressure, the spray penetration and spray angle is increased and the Sauter mean diameter (SMD) is decreased distinctly. With the increase of the injection pressure, the spray penetration and spray angle is increased and the SMD is decreased distinctly. Ensure that keeping the other conditions, rising LNG temperature and reducing the ambient pressure, the flash boiling phenomenon will be more acute and the atomization quality will be improved.
