FLUID PIPELINE EXTENDED VANE ELBOW

摘要

.angle. Figure 1 shows a system for suppressing cavitation in fluid pipeline passages such as a fluid loading arm 10, particularly of the marine type, comprising extended turning vanes 28 in the elbows 24 of the loading arm, preferably in the upstream direction from the elbow tangent point, and having a negative attack angle. The combined effect of the extended vane and the negative attack angle improves cavitation performance to a greater extent than each of these expedients when used separately. This system obtains increased flow rates without significantly increasing the system back pressure.
