متن کاملCharacteristics of clustered particles in skimming flows on a stepped spillway
Air–water flows at hydraulic structures are commonly observed and called white waters. The free-surface aeration is characterised by some intense exchanges of air and water leading to complex air–water structures including some clustering. The number and properties of clusters may provide some measure of the level of particle-turbulence and particle–particle interactions in the high-velocity ai...
متن کاملModel Investigations of Stepped Spillway
Stepped block protection has considerable potential as a low-cost method for the construction of chute spillways and the protection of embankments from erosion by overtopping flow. Stepped spillways are structurally stable, resistant to water loads and significantly increase the rate of energy dissipation on the spillway face thus eliminating or greatly reducing the need for a large energy diss...
متن کاملsurvey the effect of downstream crest chute slope on the natural air entrainment point in skimming flow in stepped spillway
abstract stepped spillways are of most important hydraulic constructions to dissipation energy of water flow. these constructions are used in opening channel to transfer water from upper level to lower level. because of considerable effect of steps on flow dissipation energy and also the resulted developments in construction of roller competed concrete rcc, the mentioned constructions have draw...
متن کاملNumerical Investigation of Pressure Load over Spillway Chutes with Vertical Curvatures
For flow conduits with mild slope and considerably large vertical curvatures the hydrostatic distribution of the pressure may be used for design proposes. However, for the spillway chutes actual pressure load over the steep slope beds with small vertical curvatures may differ from the hydrostatic pressure values. The differences in pressure load on curved bed chutes are mainly because of the ce...
