THEORETICAL STUDY OF HYDRAULIC JUMP IN CIRCULAR CHANNEL SECTION
This technical paper presents the theoretical study of hydraulic jump in circular channel section. Presuming the jump as one-dimensional free shear layer with hydrostatic pressure distribution across it, specific force equation is obtained. Using this equation and eddy viscosity closure hypothesis, analytical models for sequent depth, dimensionless profile, turbulent shear stress and energy loss for various initial Froude numbers have been obtained. Newton Raphson and Runge-Kutta Methods are used for the solution of proposed models.
The proposed models for sequent depth and energy loss are compared with the models of Richard Silvester (1964). The proposed energy loss model also provides the energy loss at any point between initial and final depth of Jump, while this provision is not available in the models of other investigators.
