Cavitation is the creation of low-pressure vapour/gas filled cavities in a fluid.

The creation of cavities becomes more difficult as the pressure increases downstream of the cavitation generator. The initial focus of
Whirlwind International was the application of cavitation in oil and gas wells for the removal of dirt and scale.
Consequently the R&D of Whirlwind International focused on generating cavitation under high-pressure conditions, in
principle up to 500 bar.

Whirlwind International uses fluid driven vibration instruments, also called hydro-vibrators, to produce a flare of cavitation
bubbles. These bubbles violently implode once they leave the direct influence area of the hydrovibrator.
The implosions cause suction and vibration effects that dislodge dirt in the inflow area of a
well or scale dep
