1. A process for controlling hydrodynamic cavitation in a fluid using the variable flow-through cavitation device with an elongated housing having an inlet and an outlet, an outer annular body disposed within and fixed to the elongated housing, the outer annular body having a plurality of channels passing radially therethrough, an inner annular body disposed concentrically in and having an exterior surface abutting with an interior surface of the outer annular body and defining an inner cylindrical chamber in fluid communication with the inlet, the inner annular body having a plurality of channels passing radially therethrough corresponding to the pluraity of channels passing through the outer annular body, and a rotating shaft fixed at one end to a rotating disk attached to the inner annular body and extending therefrom through the elongated housing to permit rotational adjustment of the inner annular body relative to the outer annular body, wherein each corresponding pair of channels forms a jet nozzle in fluid communication with the inlet and the outlet, the process comprising the steps of:
fully aligning the plurality of channels passing through the inner annular body with the plurality of channels passing through the outer annular body, wherein a flow cross-section of each corresponding pair of channels forming a jet nozzle is maximized;
pumping the fluid through the inlet at a pre-determined pump pressure of between 25 and 5,000 psi;
generating hydrodynamic cavitation in the fluid passing through the flow cross-section of each corresponding pair of channels forming a jet nozzle;
measuring an intensity of the hydrodynamic cavitation generated in the fluid;
rotating the inner annular body relative to the outer annular body rotatable such that the plurality of channels passing though the inner annular body are no longer fully aligned with the plurality of channels passing through the outer annular body and the flow cross-section of each corresponding pair of channels forming a jet nozzle is reduced, wherein the intensity of the hydrodynamic cavitation generating in the fluid is controlled through such reduction.
