Title:
CENTER PIVOT IRRIGATION GOOSENECK WITH VARYING CROSS-SECTIONAL DIAMETERS
Document Type and Number:
WIPO Patent Application WO/2018/009857
Kind Code:
A8
Abstract:
A gooseneck pipe includes a first pipe half having a first radiused centerline curve, and a second pipe half fixed to the first pipe half and having a second radiused centerline curve. The first and second pipe halves define a flow path. Cross-sectional diameters of the first and second pipe halves vary along the flow path. The varying diameters of the first and second pipe halves serve to mitigate pressure losses due in part to Dean vortices or secondary flow patterns in the flow path when a fluid is turned in the gooseneck pipe.
