ABSTRACT:
This invention relates to an apparatus and method that provides by means of circulator/impeller configuration alone the generation of a stabilized vortex in a media wherein the vortex generated is stable in its dynamic formation over a wide range of rotational circulator/impeller speeds and increasing distances beneath the surface of the media.
The apparatus and method include a charge carrying fluid media in a vessel or other containment device that is redirected within the vessel or containment device by fluid flow, by and through a circulator/impeller such that the fluid is forced to pass through an angle greater than 90 degrees but less than 180 degrees. The redirection being as a result of forces imparted to the fluid by virtue of the inventive geometry of the circulator/impeller and independent of vessel/containment device configuration or nearby wall confinements.
The improved circulator is provided with means to allow a portion of the media to be circulated to be delivered to a region beneath the circulator to thereby flush away foreign objects heavier than the media that may be present beneath the circulator.
