  • System and method to control nucleation of bubbles
    Patent number: 11654205
    Abstract: Generation of bubbles is disclosed to occur within a flow of an aqueous fluid. The bubbles may be formed within a tube of a selected diameter and the bubbles are controlled to exit the tube at a selected diameter. Generally, bubbles are formed to include a diameter of less than 1 millimeter, including less than about 20 microns.
