Heat transfer characteristics about supercritical LNG in intermediate fluid vaporizer was investigated via numerical analysis and CFD simulation

and the influences of pressure and mass flow rate were studied.The result showed that the heat transfer coefficient and the wall temperature fluctuated as the LNG temperature increased

and changing mass flow fate seemed no use about this.In addition

the simulation result showed that the heat transfer deterioration occurred when LNG was near critical region

and the main reason was the properties' sharp change near critical region.Increasing the mass flow rate seemed a effective way to avoid heat transfer deterioration.
