The circular hydraulic jump; the influence of downstream flow on the jump radius

In this study, we examine the consistency of a gravity-based predictive theory for hydraulic jump, given by Kurihara [ Proceedings Report Research Institute Fluid Engineering (Kyusyu Imperial University, 1946), Vol. 3, pp. 11–33]; Tani [J. Phys. Soc. Jpn. 4, 212–215 (1949)] with phenomenological condition at jump Rayleigh [Proc. R. London, Ser. A 90, 324–328 (1914)]; and Watson Mech. 20, 481–499 (1964)] show that in light experimental evidence, kitchen sink is incompatible condition, which must be valid. We also solution to downstream film its potential influence on jump. all practical purposes, normal flow conditions, liquid remains flat does not affect Bhagat et al. 851, R5 (2018)] gives an excellent prediction radius. For high viscosity liquids, relatively large plate, viscous dissipation could increase height and, consequently, move radius inward.
