Hydrodynamic Cavitation can occur in any turbulent fluid.
The turbulence produces an area of greatly reduced fluid pressure. The fluid vaporizes due to the low pressure, forming a cavity. At the edges of the cavity, small amounts of vapor break off. These form smaller cavities 100 nm to 3 mm in diameter. The smaller cavities implode under the high pressure surrounding them. This process of formation and collapse is called cavitation.

Cavitation is an enormously powerful process.
Conditions in the collapsing cavity can reach 5000⁰C and 1000⁰C for nanoseconds only. The implosion takes place during the cavitation process in milliseconds, releasing tremendous energy in the form of shockwaves. The power of these waves generated by the cavitation process uniformly disrupts everything in their path. Whether the waves are destructive or productive depends on Arisdyne’s design and control of the cavitation zone.

How does hydrodynamic cavitation differ from ultrasonic cavitation?
Ultrasonic cavitation is dependent on a source of vibrations. This makes ultrasonic cavitation difficult or impossible to scale up and often creates “hot spots” in the dispersion/emulsion.  The upper or lower flow rate restrictions for the CFC™ system are limited only by a pumps capacity to achieve required pressures of fluid flow continuously through the cavitation zone.

Won’t CFC™ cause my equipment to wear more quickly?
As everyone knows, uncontrolled cavitation is a very destructive force.  The CFC™ system is designed to produce only controlled cavitation.  Optimal process conditions also protect your equipment from impingement.  In fact, CFC™ systems are designed to last longer by utilizing static versus dynamic configuration. No moving parts in the device.

What if one of my reactants is a particulate?
CFC™ works equally well on solid and liquid reactants.  Solids are fractured into smaller pieces (100µm to 3µm in diameter).  Smaller particles mean a better dispersion and greater surface area.

Much research has been done on preventing cavitation. Its uncontrolled form causes damage to turbulent-flow systems.  But Arisdyne Systems’ patented hydrodynamic cavitation technology harnesses its power.

CFC™ (Controlled Flow Cavitation™) controls the location, size, density, and intensity of cavity implosions. The system is calibrated to produce optimum process conditions. Shockwaves resulting from the implosions impact the surrounding process fluid. Tiny droplets or particles result producing high-quality emulsions and dispersions.

Engineers have established that Controlled Flow Cavitation can easily achieve sheer forces above 100,000, 8-10 times greater than mere grinding can accomplish.
