Hydrodynamic cavitation is the process of vaporization, bubble generation and bubble implosion, which occurs in a flowing liquid as a result of a decrease and subsequent increase in localized pressure. Cavitation will only occur if the local pressure declines to some point below the saturated vapor pressure of the liquid and subsequent recovery above the vapor pressure.
AWE's technology produces hydrodynamic cavitation by passing a liquid through a constricted channel at a specific flow velocity. In our case of the constricted channel and unique geometry of the system, the combination of pressure and kinetic energy creates the hydrodynamic cavitation cavern downstream of the local constriction generating high energy cavitation bubbles. The tiny-sized or 'nano' bubbles that grow and then collapse at critical size very rapidly (10-6 seconds) releases extreme, but localized shock waves, heat and pressure (~ 5000K and ~1000 Atm) strong enough to break covalent bonds. Because the high local temperatures and local pressures at the surface of the bubbles happen for a very short time the overall liquid medium environment, remains at ambient conditions.
AWE's controlled cavitation is used to enhance chemical reactions and propagates certain reactions because free radicals are generated in the process due to disassociation of vapors trapped in the cavitating bubbles.
Controlling the cavitating flows in liquids is also achieved by advancing the mathematical foundation of our cavitation processes. These processes are manifested in different ways by customizing changes within the reactor, depending upon the fluid (oil, water) and the outcome we are trying to achieve.
AWE's cavitation reactors are passive devices, operate and low pressure, require NO external power, use NO chemicals with minimal/no maintenance or servicing. The internals are semi-precious metals, configured to create maximum hydrodynamic cavitation at rated pressures and maximum surface area at minimum pressure drop.
Depending on the volume desired we build our reactors to various diameters such as 2", 4", 6", 8" or even 36" that can treat anywhere from 10 gallons a minute to 10,000,000 gallons a day
