Evaluation of a novel self‐aerating, oscillating baffle column

The Canadian Journal of Chemical Engineering, 1998
AbstractWe describe the operation of a pilot scale oscillating baffle column using a self‐aeration system for oxygenation of water. The top baffle has a high constriction ratio and is sufficiently near to the surface of the water such that gas bubbles are generated. This aeration plate is coupled with a series of equally spaced low constriction orifice

Mean Air Concentration of Self-Aerated Flows

Journal of the Hydraulics Division, 1979
The purpose of this technical note is to develop a correlation between the mean air concentration and the most significant flow parameters in the fully aerated zone. Dimensional analysis is used to evaluate the relative importance of the various parameters. This approach follows somewhat that used by Kobus to examine the motion of bubbles in liquids.

Self-Aerated Flows On Chutes and Spillways - Closure

1994
The writer thanks the discusser (ANWAR 1994) for his interesting comments and information. The writer wishes to clarify three points : free-surface instabilities, calculations of the inception point of air entrainment and analogy between self-aerated flows and sediment-laden flows.

Turbulent Open-Channel Flows: Drop-Generation and Self-Aeration

Journal of Hydraulic Engineering, 1998
The self-aeration of high-velocity open-channel flows is attributed to the interaction between the turbulent flow and the liquid's free surface. In addition to self-aeration, drops are ejected out of the bulk liquid. It is often proposed that the drops are separated from the bulk by transverse velocity fluctuations.

Self-aerated Flow in Steep, Partially Filled Pipes

Journal of the Hydraulics Division, 1982
The self-aerated flow in steep and partially filled conduits of circular shape is investigated. Prototype measurements are carried out on pipelines with slopes up to 1.0 (45°) and diameters from 110–900 mm. Instruments for measuring the air concentration, the velocity of the mixture and the mixture level are described.

Measurements within self-aerated flow on a large spillway

1978
Instruments were developed and were used to obtain measurements of the most important flow parameters within self-aerated flows on the spillway of Aviemore dam. Compressibility effects within self-aerated flows are examined. It is shown that Mach numbers as large as 2 will occur in localised aerated regions on large structures.
