Abstract
A vortex ring generation device includes a casing having a gas passage and a discharge port, and an extrusion mechanism that extrudes a gas in the gas passage such that the gas in a vortex ring shape is discharged from the discharge port. V (m3) 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 Re represents a Reynolds number of the discharged gas. 500≤Re≤3000 and 0.5≤L/D≤2.0.
