Abstract (en)

Method and apparatus are disclosed which are used to mix two fluids, two gases, or a fluid and a gas. The preferred embodiment is useful primarily for the aeration of water but can be used to mix any gas with a liquid. The method involves creating relative movement between an elongate element and a fluid whereby a low-pressure area will be developed on the lee side of the element. The gas is then admitted to the low-pressure area and bubbles are formed. The element is preferably pointed to form a spike, and the bubbles are moved along the spike by a component of the relative motion toward the tip. When the bubble reaches the tip it will be detached and entrained in the fluid. When a plurality of spikes is used, significant efficiencies are observed. One embodiment employs spikes mounted to a rotating body and other embodiments use arrays of parallel spikes.
