Characteristics of Hydraulic Jump
The effect of an abruptly expanding channel on the main characteristics of hydraulic jump is considered experimentally. The present study was made for supercritical flow of Froude number varying between 2 to 9 and approach to expanded channel width ratios 0.4, 0.5, 0.6 and 0.8. Physical explanations of the variation of these characteristics under varying flow conditions are discussed based on t...
متن کاملForced Hydraulic Jump by One and Two Continuous Sills in a Horizontal Stilling Basin.
Forced hydraulic jump in a horizontal stilling basin with one and two continuous sills at the downstream end of an ogee standard weir was investigated. Experiments were completed on sills of five different heights which were fixed at two different distances from the toe of the weir. The main characteristics of the jump such as the sequent depth ratio, relative roller length, and relative ener...
متن کاملThe Hydraulic Jump In Two Dimensions
The first quantitative calculation of the position of the hydraulic jump was carried out a few years ago by Bohr et.al. Since this is the only calculation of the jump, we have analysed it from a slightly different point of view. Our results are similar to those of Bohr et.al.
متن کاملThe Hydraulic Jump in Liquid Helium
We present the results of some experiments on the circular hydraulic jump in normal and superfluid liquid helium. The radius of the jump and the depth of the liquid outside the jump are measured through optical means. Although the scale of the apparatus is rather small, the location of the jump is found to be consistent with the assumption that the jump can be treated as a shock, if the surface...
