1. A jet nozzle formed on an inner surface of a combustor to supply fluid into an interior of a liner of the combustor in a direction intersecting with a progress direction of combustion gases primarily combusted in a combustion chamber, the jet nozzle comprising:
a body section, extending in a longitudinal direction, provided with a fluid inlet on a first end, through which fluid is introduced, and a fluid outlet on a second end, through which the fluid introduced through the fluid inlet is discharged while generating a vortex; and
a baffle section formed on and extending inward from an inner peripheral surface of the second end of the body section and configured to enhance the generation of a counter-rotary shear layer vortex in the fluid discharged out of the fluid outlet through the body section,
wherein the baffle section is provided to opposingly protrude from two opposing peripheral portions of the second end of the body section toward a center portion of a circle defined by the second end of the body section,
wherein the baffle section is formed on the inner peripheral surface of the second end of the body section such that the baffle section extends in an extension direction which is parallel to a circumferential direction of the circle from one circumferential end to an opposite circumferential end and has a substantially constant thickness, measured in the longitudinal direction, from the one circumferential end to the opposite circumferential end;
wherein the baffle section comprises a first integral baffle part provided at a first side on the second end of the body section, and a second integral baffle part provided at a second side on the second end of the body section, the first side and the second side being opposite each other, and wherein the first baffle part and the second baffle part are circumferentially spaced apart.
