Zusammenfassung:In a vortex ring generation device, when V (m3) represents an extrusion volume, D (m) represents a diameter of the discharge port (25), L (m) represents a length of a cylinder having the diameter D and the volume V, and Re represents a Reynolds number of the discharged gas, relationships of 500 ≤ Re ≤ 3000 and 0.5 ≤ L/D ≤ 2.0 are satisfied.
