Abstract
PURPOSE: To prevent generation of vortex flow for certain with a small amount of sprayed water, by providing a water stream jetting device which jets a water stream above the water level of a water tank.
CONSTITUTION: A water flow jetting device 11 which jets out a water flow on to the water level of a water tank is installed, and it jetts out a suitable amount of water flow to a place on the water level where a vortex flow develops. By this arrangement the water flow jets fly through the air and strikes directly the water level in the vicinity of which a vortex flow develops. Because the momentum of the jet effectively changes the surface flow of the water at the vortex flow, a small amount of water spray makes sure that development of vortex flow is suppressed.
