1. A device for producing Hydrogen-enriched slush Liquified Natural Gas (LNG) fuel, the device comprising:
a vortex tube including a vortex chamber disposed inside therein, and a plurality of radial inlets installed on an outer surface of the vortex chamber through which a mixed fluid flows;
a swirl generator provided inside the vortex chamber for the mixed fluid to flow inside the vortex tube and to cause a swirling motion; and
a nozzle disposed on a left side of the swirl generator, wherein a flow field is formed when pressure decreases to a left direction from the central axis of the vortex tube and pressure increases in a right direction from the central axis of the vortex tube, a first fluid discharges through a main tube, to a right end of the vortex tube, and a second fluid, which is lower than the first fluid in temperature discharges through a fluid vent on a left side of the vortex tube.
