| Abstract | ||
| Wlien one or more of tlie vents of a regulator is opened or dosed during maintenance, asymmetric flow occurs and a hydraulic jump may be formed. The characteristics of the hydraulic jump formed just upstream of asymmetric expansion are investigated both theoretically and experimentally. The derived theoretical equations for tlie relative deptli and the relative energy loss ofjump are based on the application of the basic flow equations. Also, the length ofjump was predicted empirically. The theoretically and empirically developed equations were compared witli the experimental observations. Good agreement was obtained. Tlie relative static pressure head at the side of tlie expansion was analyzed. The analysis of results revealed that the relative deptli and the relative length ofjump increased witli the increase of tlie expansion ratio while the relative energy loss was decreased with the increase of the expansion ratio. It was proved tliat the effect of the relative static pressure head could be neglected at high values of Froude numbers and high expansion ratios. | ||
