Abstract: Various embodiments of a system and process for reducing the size of solid particles are disclosed. In one embodiment the system includes a cavitation processor and a comminution processor in physical communication with one another to reduce the size of solid particles. In another embodiment, a process for reducing the size of solid particles includes passing the solid particles sequentially through a cavitation processor and a comminution processor which are in physical communication with one another. Examples of solid particles which may be used in the system and process herein, include pharmaceuticals, foods, inks and paints.

Abstract: A device and method for creating hydrodynamic cavitation in fluid is provided. The device includes a fluid passage having at least two local constrictions of flow provided in a parallel relationship therein, wherein each local constriction of flow configured to generate a hydrodynamic cavitation field downstream therefrom. The at least two local constrictions of flow can include concentrically arranged annular orifices.

Abstract: Methods and devices for mixing fluids are described. One exemplary method includes producing hollow cylinders of fluid, flowing the cylinders toward one another along the surface of a cylinder, and colliding the cylinders head-on to produce a radial outflow of fluid and cavitation bubbles.
