Abstract

In the paper theoretical analysis of the phenomenon of impingement of a circular liquid jet upon a plate has been carried out. In the considered case, spreading of the liquid on a plate is caused by the inertia and gravity forces. For supercritical liquid flow, in certain conditions a hydraulic jump is formed, The circular hydraulic jump exhibits behaviour quite different from that commonly observed in planar jets. In the paper a new theoretical model of the phenomena of hydraulic jump has been formulated. Theoretical treatment have been compared with own and other available experimental data.
