Experimental Measurements of Multiple‐Jet Induced Flow

Abstract

Experimental results are confirmed for theoretical predictions of a vortex model for the two-dimensional inviscid flow generated by a line of submerged, turbulent, shallow water jets in a coflowing current. The experiments are performed in a large shallow water basin in which a strong uniform current can be produced and boundary effects are negligible. The vortex model is validated against detailed velocity measurements at and downstream of the momentum source line. Observations of surface flow patterns show that, depending only on the ambient current to ultimate slipstream velocity ratio, distinct flow regimes ranging from a strong inwardly directed sink flow to a smooth contracting slipstream can result.
