Abstract:
An apparatus for producing and sustaining a vortex flow field, said apparatus comprising:a flow field chamber;a chamber axis extending through said chamber;a side wall having an inner surface encircling said chamber axis;a first chamber end extending from said side wall and intersected by said chamber axis, said first chamber end being substantially closed;a second chamber end extending from said side wall opposite said first end and being intersected by said chamber axis, said second chamber end having a restricted fluid outlet opening;one or more fluid inlet openings in said side wall near said second end for directing a fluid into said chamber to create a flow substantially tangent to said inner surface; and said chamber being substantially free of structure that would prevent said fluid from flowing in a first vortex pattern along said side wall toward said first chamber end and then flowing in a second vortex pattern rotating in the same direction as said first vortex pattern from said first chamber end toward said second chamber end substantially along said chamber axis.
