This invention discloses a vortex nozzle based on the boundary layer effect. It includes an inlet structure, a vortex assembly, and an outlet structure. The vortex assembly consists of at least two coaxial vortexes stacked together, each with a central hole that forms an axial jet channel. The wavy surfaces of adjacent vortexes form a curved channel that converges towards the central hole, with the curved surfaces forming troughs at the edge of the central hole. The axial spacing h is less than the diameter D of the central hole. Water enters the curved channel tangentially from the outer edge, smoothly changes direction due to the boundary layer effect, and forms a vortex at the central hole, resulting in an axial jet that achieves a near 90° turn. When used for rotary drive, at least two circumferentially distributed nozzles spray in opposite directions along the tangent, forming a force couple. This invention features low energy loss, concentrated jet, and strong reaction force.
