<p>PROBLEM TO BE SOLVED: To provide a vortex generator in which a flowing medium goes to controlled vortex motion.SOLUTION: The vortex generator is designed to make a medium reach the controlled vortex motion and comprises an injection port part 1 which is a hollow state and which makes the medium reach the vortex generator. The injection port part is formed of a curved rotation symmetry mold cavity. In addition a vortex chamber 401 in which the vortex motion is established is attached to the injection port part 1. The injection port part 1 includes at least one spiral shaped conical channel for making the medium reach the vortex chamber from the rotation symmetry mold cavity. The vortex chamber is a trumpet shape or an oval shape.</p> |
