Patent ID: 8820414

Claim:
A method of improving flow stability for a multiphase fluid flowing through a tubular element, comprising arranging a flow control device along a flow path within the tubular element, wherein the flow control device is positioned with an axis thereof in a direction substantially parallel with a longitudinal axis of the tubular element, the flow control device comprising: a housing; an inlet arranged within the tubular element on an upstream side of the flow control device; an outlet arranged within the tubular element on a downstream side of the flow control device; and a movable body provided within the housing along an internal flow path through the flow control device from the inlet to the outlet, the body being arranged such that changes in any of velocity, properties and/or composition of the fluid flowing along the internal flow path result in changes to the forces acting on the body as a result of the Bernoulli principle, thereby adjusting the flow of fluid through the flow control device.
