Dynaflow, Inc. has developed large flow rate bubble generators based on its two patented DynaSwirl® and StratoJet® technologies. The DynaSwirl® bubble generator generates a highly rotating flow to create a very low pressure at the center of a vortex which cavitates. This cavitation results in vortex breakdown near the orifice and generation of very fine bubbles. Air or other gases can be easily introduced into the generator to enhance gas transfer. The StratoJet® bubble generator utilizes a passive acoustic resonance created by flow interaction with the nozzle and upstream chambers to induce the formation of large vortical ring cavities which break up to generate very fine bubbles.
Both DynaSwirl® and StratoJet® bubble generators are scalable and versatile, and can be made to different scales and flow rates and can be custom designed and fabricated to meet the customer specific application requirements. The bubble generators also allow production of bubble sizes ranging from nanometers to millimeters depending on the configuration and application. Selection of sizes and pump capacities enables these generators to produce from very small to very large flow rates and to spread over a larger area.
The Dynaflow’s bubble generators have applications such as
- Aeration in fish farms.
- Waste water treatment for enhanced aerobic reaction.
- Bubble columns with enhanced mixing
- Protection against cavitation or underwater shock
- Sound insulation, …etc.
