Relationships between a roller and a dynamic pressure distribution in circular hydraulic jumps

Fluid Dynamics 2009-11-06 v1 Computational Physics

Abstract

We investigated numerically the relation between a roller and the pressure distribution to clarify the dynamics of the roller in circular hydraulic jumps. We found that a roller which characterizes a type II jump is associated with two high pressure regions after the jump, while a type I jump (without the roller) is associated with only one high pressure region. Our numerical results show that building up an appropriate pressure field is essential for a roller.
