Abstract
Official abstract text for this publication.
An example flow control device includes a body having an inlet and an outlet and a flow chamber extending therebetween. The flow chamber is configured to convey a fluid composition comprising a desired and an undesired fluid from the inlet to the outlet. A nozzle is arranged at the outlet and in fluid communication with the flow chamber, and at least one helical groove is defined along at least a portion of an axial length of the flow chamber. The at least one helical groove is configured to impart rotational motion to the fluid composition and thereby force at least some of the undesired fluid into the at least one helical groove and slow a progress of the undesired fluid along the axial length of the flow chamber.
First claim
Opening claim text (preview).
The invention claimed is: 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…
