Abstract
A tornado generating method and apparatus in accordance with the present invention can generate a tornado without forming an enclosed space and forcedly generating a spiral flow therein, and an object of the present invention is to ensure a wide collection range with vortex convergency of the tornado. In particular, a fluid flow in a fixed direction is brought into contact with a discontinuous fluid flow flowing in the reverse direction, remaining in a static state and flowing with a different rate relative to said fluid flow, or an object, to form a discontinuous plane therebetween. By sucking a fluid from at least one end of the axial direction of a plurality of vortexes generated on the discontinuous plane, the plurality of vortexes can be converged to form a core of a tornado in a free space, thereby artificially generating a tornado toward the sucking direction and a wide range of collection is ensured by the vortex convergency of the tornado.
