Abstract
A bubble generator for producing a stream of uniform bubbles includes components which are stationary. The bubble generator includes a container or plenum having an inclined face plate with a plurality of nozzles positioned thereon. The nozzles are elongated slots positioned in the face plate and have an insert disposed within the slot with edges that extend within the plenum and above the surface of the face plate for facilitating formation of a liquid film across the slot. The insert may have an extension positioned at an upper portion for providing lift and buoyancy to the bubbles. A liquid supply manifold is positioned above the nozzles and directs a flow of liquid to the nozzles. As the liquid flows across the slot and is contained within the insert, a film forms across the slot without the need for any dipping or priming means. An air supply then directs air into the liquid film and produces the stream of bubbles.
