Résumé

The hydraulic jump is the turbulent transition from supercritical to subcritical flow. The aim of this work is to contribute to a best understanding of the behavior of hydraulic jump in a symmetrical triangular channel of central angle of 90°. New experiments were conducted to quantify its characteristics for a wide range of Froude numbers (2 < F1 < 11). The analysis of the experimental results shows the insufficiency of the equations already suggested, deducted from the half triangular channel studied by Hager and Wanoschek (1985). The influence of the upstream sequent depth on the features of the hydraulic jump and especially the surface profile is considered.
Some relationships, translating the sizes of the characteristics of the hydraulic jump in asymmetrical triangular channel, are presented in dimensionless terms, in order to show their general practical validity. The effects of the cross-sectional are investigated as well.
This research is applied particularly in the conception of dams’ stilling basins.
