- Abstract
- A modeling of a hydraulic-gun-aerator is proposed to set up a design procedure for
such devices. The aerators are used to destroy any thermal stratification that are
responsible for the degradation of water quality of lakes. The aerator produces ascending
flow by using air bubbles released instantly near the bottom of the lake into a cylindrical
pipe installed vertically. Differently form the diffuser-aerators, they can pull up the cold,
oxygen depleted water directly to the region of the free surface, and they are believed to
work effectively especially for relatively deeper lakes. Their design procedure has not been
established yet though, and we propose a model focusing on the exit flow velocity at the
top of the aerator through the examination of presently operating devices.
