Dynaflow, Inc. introduces the StratoJet® microbubble generator based on its StratoJet technology. The generator utilizes a passive acoustic resonance created by flow interaction with the nozzle and upstream chambers to induce the formation of large vortical structure, which break up cavities to generate very fine bubbles. A special design allows users to introduce air or other gases to enhance gas transfer. The units can generate high-void fraction bubbly flows, dominated by very small, microsized bubbles, are scalable and versatile, can be made to different scales and flowrates and can be custom designed and fabricated to meet specific-application customer requirements. http://www.dynaflow-inc.com, ctsung@dynaflow-inc.com
