A theoretical prediction of rotating waves in Type-I hydraulic jumps

Publication date: Available online 9 October 2018Source: Physics Letters AAuthor(s): Arnab K. Ray, Niladri Sarkar, Abhik Basu, Jayanta K. BhattacharjeeAbstractThe rotation of polygons in a Type-II hydraulic jump prompts us to look for a rotational feature in the Type-I hydraulic jump. Coupling the radial and azimuthal flows breaks the azimuthal symmetry of the shallow-water circular jump. An unstable rotating wave along the circumference of the jump is possible with a kinematic viscosity of very small order, whose upper threshold value is less than the kinematic viscosity of water.
