Fluid flow control using channels

The subassembly of claim 4, wherein the at least one fluid property comprises:

• Reynolds number of the fluid;
• fluid density;
• fluid velocity;
• or
• fluid viscosity.

A subassembly for a fluid flow control device adapted to be disposed in a subterranean wellbore, the subassembly comprising:

• a chamber having an exit opening:
• a first channel for directing fluid from a first inlet toward the chamber;
• a second channel for directing fluid from a second inlet toward the chamber;
• and
• a side channel for allowing fluid to flow from the second channel to the first channel to affect fluid flowing in the first channel;
• a primary channel in fluid communication with the first channel, the primary channel being configured for directing fluid toward the exit opening;
• a first diverted channel in fluid communication with the first channel;
• and
• a second diverted channel in fluid communication with the second channel,
• wherein the first diverted channel and the second diverted channel are configured for directing fluid toward a tangential opening of the chamber,
• wherein the side channel is adapted to allow an amount of fluid to flow from the second channel to the first channel to guide fluid to flow toward the primary channel, the amount of fluid being based on the at least one property of the fluid.

The channel subassembly of claim 20, wherein the fourth channel includes:

• a first primary channel in fluid communication with the second channel;
• and
• a second primary channel in fluid communication with the first channel;
• and
• a diverted channel for directing fluid toward a tangential opening of the chamber, the diverted channel being in fluid communication with the first channel,
• wherein the first primary channel and the second primary channel are configured for directing fluid toward the exit opening,
• wherein the side channel is adapted to allow an amount of fluid to flow from the second channel to the first channel to guide fluid to flow toward the diverted channel, the amount of fluid being based on the at least one property of the fluid.

The fluid flow control device of claim 15, wherein the at least one fluid property comprises:

• Reynolds number of the fluid;
• fluid density;
• fluid velocity;
• or
• fluid viscosity.

The channel subassembly of claim 20, wherein the fourth channel is a primary channel in fluid communication with the first channel, the primary channel being configured for directing fluid toward the exit opening;

• a first diverted channel in fluid communication with the first channel;
• and
• a second diverted channel in fluid communication with the second channel,
• wherein the first diverted channel and the second diverted channel are configured for directing fluid toward a tangential opening of the chamber.

A fluid flow control device configured for being disposed in a wellbore, the fluid flow control device comprising:

• a vortex chamber having an exit opening;
• a fluid delivery subassembly;
• and
• a channel subassembly positioned between the vortex chamber and the fluid delivery subassembly, wherein the channel subassembly comprises:
• a first channel for providing a first flow path for fluid from the fluid delivery subassembly toward the chamber;
• a second channel for providing a second flow path for fluid from the fluid delivery subassembly toward the chamber;
• a side channel for providing fluid communication between the first channel and the second channel;
• a first primary channel in fluid communication with the second channel;
• a second primary channel in fluid communication with the first channel;
• and
• a diverted channel for directing fluid toward a tangential opening of the chamber, the diverted channel being in fluid communication with the first channel,
• wherein the first primary channel and the second primary channel are configured for directing fluid toward the exit opening.

A channel subassembly for a fluid flow control device adapted to be disposed in a subterranean wellbore, the channel subassembly comprising:

• a first channel for directing fluid from a first inlet in fluid communication with a fluid delivery subassembly toward a chamber having an exit opening;
• a second channel for directing fluid from a second inlet in fluid communication with the fluid delivery subassembly toward the chamber;
• and
• a side channel for allowing an amount of fluid to flow from the second channel to the first channel to direct fluid flowing in the first channel toward a fourth channel that is configured to allow fluid to flow to the chamber, wherein the amount of fluid is based on at least one property of the fluid.
