Abstract
A vortex ring generation device includes a casing and an extrusion mechanism. The casing has a gas passage and a discharge port. The extrusion mechanism extrudes gas in the gas passage such that the gas in a vortex ring shape is discharged from the discharge port. V (m) represents an extrusion volume, D (m) represents a diameter of the discharge port, L (m) represents a length of a cylinder having the diameter D and the volume V, and U (m/s) represents a discharge flow rate 0.045≤D≤0.135, 0.15≤L≤0.35, and 3≤U≤5.
