Aeration performance of hydrodynamic flow regulators
Water Science and Technology, 2013 Hydrodynamic flow regulators are used in environmental engineering as a replacement for traditional flow throttling devices. They are extremely efficient, reliable and free from the common disadvantages of traditional devices. Recent research by the authors indicated that the atomization of a liquid by hydrodynamic flow regulators accelerates ...

AERATED FLOW CHARACTERISTICS ON STEPPED CHANNELS
PROCEEDINGS OF HYDRAULIC ENGINEERING, 2005 Stepped channels are effective for dissipating the energy of supercritical flows that occur at steep channels, dams, weirs, and drop structures. As stepped channel flows are characterized as aerated flows, it is important to estimate the energyh ead of the aerated flow for a hydraulic design of the stepped channel.

Turbulence in continuous flow surface aeration systems [PDF]
Water Science and Technology, 2016 Turbulence characteristics in an optimal continuous surface aeration system were investigated in this study. The experimental system consists of a rectangular tank, where flow is driven by equally spaced aerators placed on the liquid surface. The mass-transfer coefficient and turbulent parameters at the tank's inlet and outlet were measured to enable ...
