Bubble size is controlled by an air pump and is kept roughly constant in the present study [diameter d = (5.4±0.3) mm].
Dense bubble flow in a silo: an unusual flow of a dispersed medium
The author’s method has two working versions: (1) the first variant the warm (hot) atmospheric air is lifted by the inflatable tube in a high altitude and atmospheric steam is condenced into freswater: (2) in the second version, the warm air is pumped 20-30 meters under the sea-surface.
