Studies of Scour Patterns Produced by Rotating Jets in a Flow Field.
Abstract
A series of laboratory experiments were conducted to determine the scouring properties of submerged jets. Five cases were considered: (1) a jet rotating in still water; (2) a fixed jet in a fluid moving parallel to the jet (coflow); (3) a fixed jet in a fluid moving perpendicular to the jet (crossflow); (4) a fixed jet in a fluid moving against the jet (counterflow); and (5) a jet rotating in a moving fluid. In each case, dimensionless equations were developed to estimate the applied shear stress at the bed as a function of distance from the jet. The test results showed that a fixed coflow jet scoured the greatest distance, and rotating a jet in a mean flow scoured the greatest area. A summary of test results for each jet/current combination is provided in tabular form.
