aerated flow การใช้

• The mechanism of silt abrasion is studied . specific contents are summarized as following : 1 . the research results of turbulent flow , sediment - laden , aerated flow and silt abrasion are introduced
• The results show that the correlation dimensions are different in different current conditions . it is indicated that sediment - laden and aerated flows are not completely stochastic , possessing its intrinsic order
• The definition and calculation of fractional dimension is introduced briefly . the pressure fluctuation signals are processed by reconstructing the phase space for sediment - laden and aerated flow . the correlation dimensions are calculated for sediment - laden flow , clear water and aerated flow
• The water current flows over the top of the dentoid baffle to the hydraulic jump as additional momentum . while it is cooperated with a stilling basin , the flowing condition emerged in the basin may be improved greatly and the length and downstream water depth required by the basin can be decreased to a great extent . such an appliance may be also used to solve the problems of insufficiently dissipating water flow energy and aerating flow , which are often faced with those hydraulic engineering constraction as acted by high waterhead , great specific discharge and low froude number
• The turbulent characteristics of high - velocity sediment - laden and aerated flow are more other than the clear water flow of single - phase and current of low speed . in a special circulating system with high velocity flow , some flow parameters such as boundary shear stress and pulsation pressure are measured . an investigation is made on the turbulent characteristics of the three - phase flow of water , air and sand
