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...

Local surface aeration at hydraulic structures

In open channel flows, local surface aeration processes occur mainly at weirs and drop structures and in hydraulic jumps. Air entrainment in the wakes of bluff bodies is observed only in high speed flows. In water pollution abatement, the natural gas exchange at the free surface is sometimes not sufficient to balance the oxygen consumption due to pollutants. In such cases, local aeration is nee...

Efficiency of the Nam Theun 2 hydraulic structures on water aeration and methane degassing

Release of hypolimnetic water from man-made reservoirs can be a problem for downstream rivers. These effects can be significant mainly during the first years after the reservoir impoundment, especially in thermally stratified reservoirs favouring the release of anoxicmethane-richwater. In tropical areas, higher temperatures decrease the oxygen solubility and enhance chemical processes responsib...
