Abstract:
1. A flow control device, comprising: a body having an inlet and an outlet and a flow chamber extending therebetween, the flow chamber being configured to convey a fluid composition comprising a desired fluid and an undesired fluid from the inlet to the outlet, wherein the undesired fluid is at least one of more dense and less viscous than the desired fluid; a nozzle arranged at the outlet and in fluid communication with the flow chamber; and at least one helical groove defined into an inner surface of the flow chamber along at least a portion of an axial length of the flow chamber, the at least one helical groove being configured to impart rotational motion to the fluid composition to separate a portion of the undesired fluid from a portion of the desired fluid and force the portion of the undesired fluid into the at least one helical groove to slow a progress of the undesired fluid along the axial length of the flow chamber.
