Reduction of friction of a Flow of viscous Fluid in a Conduit

摘要

A device for reducing the friction of a Flow of viscous Fluid in a Conduit includes a Body (10, 110) positionable to define at least a segment of a Flow Path of the viscous Fluid in or Adjacent to The Conduit, a Cavity (40, 140) in the body to retain Fluid Lu Manufacturer, and at least one Port (42, 142) in the body to supply Lubricating Fluid in the Cavity.A FLUID OUTLET (48, 148) from the Cavity provides a Lubricating Fluid to flow path downstream to form a Lubricating Film around the viscous Fluid that flows in the same. The Settlement of output Fluid comprises a substantially Continuous opening or Ring with Openings close together around the flow path.The Cavity includes a set of Passages in the body that includes a Plurality of elongated Passages (55. 155) that extends around the flow path that collectively are effective to reduce the pressure variation and therefore the speed variation of the Fluid LUBRICANT provided along the line of departure. A corresponding method is also described.
