Abstract

Fluid flow control devices comprise a body including a central aperture extending along a longitudinal axis therethrough and a plurality of channels extending from an outer sidewall of the body to an inner sidewall of the body. At least one first channel may intersect at least one other channel. Fluid flow control systems, methods of forming fluid flow control devices, and methods of flowing a fluid through a fluid flow control device are also disclosed.

Claims

1. A method of flowing a fluid through a fluid flow control device, comprising:

flowing a fluid through a first substantially arcuate channel that extends from an outer surface of a body to an inner surface of an aperture extending through the body;

flowing a fluid through at least one second substantially arcuate channel that from the outer surface of the body to the inner surface of the aperture, the at least one second substantially arcuate channel intersecting the first substantially arcuate channel, the first substantially arcuate channel and the at least one second substantially arcuate channel being bounded by channel sidewalls extending smoothly and continuously from the outer surface of the body to the inner surface of the aperture; and

impinging the fluid flowing through the first substantially arcuate channel into the fluid flowing through the at least one second substantially arcuate channel, wherein the intersecting channels fit simultaneously through an area having an approximate width of a single channel.

2. The method of claim 1, wherein flowing the fluid through the first substantially arcuate channel and through the at least one second substantially arcuate channel comprises flowing the fluid through channels being bounded by parallel channel sidewalls.

3. The method of claim 1, wherein flowing the fluid through the first substantially arcuate channel and through the at least one second substantially arcuate channel comprises flowing the fluid through the first substantially arcuate channel and through the at least one second substantially arcuate channel from the outer surface of the body to the inner surface of the aperture.

4. The method of claim 1, wherein flowing the fluid through the first substantially arcuate channel and through the at least one second substantially arcuate channel comprises flowing the fluid through the first substantially arcuate channel and through the at least one second substantially arcuate channel from the inner surface of the aperture to the outer surface of the body.

5. The method of claim 1, wherein flowing the fluid through each of the first substantially arcuate channel and the at least one second substantially arcuate channel comprises flowing the fluid through at least four intersections with other channels.

6. The method of claim 1, wherein flowing the fluid through the first substantially arcuate channel and through the at least one second substantially arcuate channel comprises reducing the pressure of the fluid.
