Résumé / Abstract

The paper deals with the theoretical study of hydraulic jump in trapezoidal, channel section. Presuming the jump as one-dimensional free shear layer with hydrostatic pressure distribution across it and using eddy viscosity closure hypothesis, analytical models for sequent depth, dimensionless profile, turbulent shear stress distribution and energy loss for various initial Froude numbers have been obtained. The proposed models for sequent depth and energy loss are compared with the models ofR Silvester7. The proposed energy loss model provides the energy loss at any point between initial and final depths of the jump while this provision is not available in the models of other investigators. Furthermore, eddy viscosity closure approach has been used herein. Newton Raphson and Runge-Kutta methods are used for the solution of the proposed models.
