Abstract
An array of parallel pipes, each having ports through which jet-like air streams exit, are arranged so that a peripherally directed air curtain is formed. The posts are shielded at both ends, and one end is provided with a chimney along a central axis of the air by which air or fluid is removed. By giving the air curtain a centrifugal force, a negative pressure is produced along a central core, and a spiral flow is produced, creating an artificial tornado.
Claims16
The method of generating an artificial tornado comprising the steps of creating a continuous fluid curtain uniformly spaced from and circulating about a central axis, withdrawing fluid from one end of said axis to form a vacuum core along said axis, and simultaneous creating a spiral flow of fluid within the space between said fluid curtain and about said central axis, said fluid curtain, spiral fluid flow and withdrawal or fluid cooperating to accelerate the fluid flow within said array to produce a tornado.
The method of generating an artificial tornado comprising the steps of arranging a plurality of pipes, each provided with ports spaced along its length in an array about a central axis so that said ports are directed in a common direction toward the next adjacent pipe, shielding said array at at least one end of said pipes by a cover plate having an exhaust opening aligned with the central axis, blowing fluid through said pipes to form an air fluid curtain continuously about the periphery of said array, creating an air flow along the central axis toward said exhaust opening, and creating a rotary air flow within said array about said central axis and simultaneously removing fluid from said exhaust opening to accelerate the fluid into a tornado within said array.
Apparatus for generating an artificial tornado comprising a plurality of hollow pipes, each pipe having a plurality of ports along their length, said pipes being arranged parallel to each other in a spaced array about a central vertical axis, said array having at least one end shielded by a cover plate having a discharge opening aligned with the central axis, said pipes being arranged so that the ports are pointed parallel with respect to each other and toward the next adjacent pipe in a common direction horizontal to the central axis;
- means for blowing fluid through each of said pipes to form a continuous circulating fluid curtain in the horizontal direction about the central axis, said fluid curtain separating the air space within said fluid curtain from the air space outside said fluid curtain;
- means for blowing fluid along said central axis to create an axial fluid flow within the fluid curtain, said axial flow cooperating with said horizontally circulating fluid to create a centrifugal fluid stream between said fluid curtain, and means for selectively regulating the relative strength of said circulating fluid and said axial fluid flow to cause said centrifugal fluid stream to flow spirally about the central axis and exhaust through said discharge opening in said cover plate.
