Abstract
An apparatus for forming a vortex wherein the vortex is typically formed of a fluid injected into a cavity formed in a cup-shaped member. The interior surface of the cup is formed of two discreet sections, a cylindrical section and a hemispherical section. An inlet port provides an ingress for fluid into the cavity. The fluid strikes the hemispherical surface upon entering the cavity and is redirected or diffused such that the fluid forms a vortex. The cylindrical section aids to stabilize the vortex enabling the vortex to extend above the surface of the cup-shaped member prior to degenerating.
Claims20
An apparatus for forming a vortex comprising:
- a member having a cavity therein, said member including an outer surface wherein said cavity communicates with said outer surface to form an opening, such that said vortex is formed within said cavity and exits said cavity through said opening;
- said cavity further defining a surface and said member having a passageway therein, wherein said passageway intersects with said surface to form an inlet port at the intersection of said surface and said passageway;
- said surface of said cavity including a diffuser surface and a stabilizer surface, said stabilizer surface positioned adjacent said diffuser surface such that said vortex is formed by contact of a fluid with said diffuser surface and is stabilized by said stabilizer surface prior to exiting the cavity through the opening adjacent said outer surface;
- and
- said cavity having a central axis, said vortex formed about said central axis, a cross-sectional shape of said cavity taken along a plane encompassing said central axis is such that the diffuser surface is arcuate and the stabilizer surface is linear and parallel said central axis.

A method for forming a vortex comprising:
- directing a fluid into a member having a cavity therein, said fluid entering said cavity and striking an arcuate diffuser surface;
- said arcuate diffuser surface redirecting the flow of said fluid to include a rotational component and an axial component wherein said arcuate diffuser surface redirects said fluid to form a fluid vortex;
- passing said fluid vortex through a stabilizer surface positioned adjacent said arcuate diffuser surface, said stabilizer surface acting on said vortex in a manner such that degeneration of said vortex upon exiting said cavity is reduced.
An apparatus for forming a vortex comprising:
- a member having a cavity therein, said cavity including an opening communicating with an outer surface of said member, said cavity having a diffuser section including an arcuate surface which forms a fluid emitted from an inlet pen and striking the arcuate surface into a vortex;
- and
- a separate stabilizer section having a surface parallel a central axis of the cavity positioned adjacent said diffuser section wherein said vortex formed in said diffuser section travels through said stabilizer section prior to exiting said cavity through said opening.
An apparatus for forming a vortex comprising:
- a cup, said cup having a cavity formed of a cylindrical surface and hemispherical surface;
- a passageway positioned tangential to said hemispherical surface wherein said passageway terminates at said hemispherical surface forming an inlet port opening into said hemispherical surface, said inlet port forming an ingress for a fluid which upon striking said hemispherical surface swirls about in said cavity to form a fluid vortex.
An apparatus for forming a vortex comprising:
- a member having a cavity therein, said member including an outer surface wherein said cavity communicates with said outer surface to form an opening, such that said vortex is formed within said cavity and exits said cavity through said opening;
- said cavity further defining a surface and said member having a passageway therein, wherein said passageway intersects with said surface to form an inlet port at the intersection of said surface and said passageway;
- said surface of said cavity including a diffuser surface and a stabilizer surface, said stabilizer surface positioned adjacent said diffuser surface such that said vortex is formed by contact of a fluid with said diffuser surface and is stabilized by said stabilizer surface prior to exiting the cavity through the opening adjacent said outer surface;
- and
- said diffuser surface is of a contour such that a fluid entering said cavity through said inlet port and striking said diffuser surface is redirected by said diffuser surface to include both a rotational component and an axial component.
