Abstract

Hydraulic jump is one of the most important phenomena in a rapid changing flow. It occurs when flow change from supercritical into subcritical and there is an increase in the depth over a small distance. In the present study, the characteristics of hydraulic jumps in contractions and expansions with curved walls were investigated for five Froude numbers in the range 5.8

Keywords

Contraction, expansion, hydraulic jump, instantaneous velocity, reynolds stresses.
