TORNADO PHENOMENON GENERATOR, AND ITS DEFLECTION SYSTEM AND JETTING STREAM SHAPE

摘要

PROBLEM TO BE SOLVED: To solve the problems that in a conventional tornado generating technique, a blow-out port is installed on the side surface or the bottom section of an apparatus, and a suction port is installed on the top section, and therefore, the structure is complicated, and the variation of a tornado is scarce, and also, only a simple tornado-like eddy is obtained by a container having a cylindrical shape, and in either one of the technics, various kinds of phenomena such as a whirlwind, a tornado and a down-burst cannot automatically be generated in cycles, and especially in the generation of a tornado in a rectangular container or in a room being considered to be optimal for observation-appreciation, there is a problem such as a difficulty in the generation, and the solution is required.;SOLUTION: A jetting stream from a propeller which is set at the center of the top layer of a container is deflected into right and left two streams by using a plate and a stream separating plate. By creating the two irregular fan-like jetting streams, a rotating stream which is indispensable for the creation of a tornado generation in the container can be obtained, and the generation of the tornado phenomenon in a rectangular container is made possible.;COPYRIGHT: (C)2009,JPO&INPIT
