Ultrasonic Flow Through Reactors
Emulsifying of Substances |

Ultrasonic cavitation is a result of high frequency sound waves introduced by means of a series of transducers mounted to the exterior of the tube. The intense sound travels throughout the tube and cerates waves of compression and expansion in the liquid. in the compression wave, the molecules are tightly compressed together. Conversely in the expansion wave , the molecules are rapidly pulled apart. The expansion is so dramatic that the molecules are ripped apart creating microscopic vacuoles. The vacuoles are not seen by the naked eye since they are so small and exist on for a millisecond of time. As the pressure around the vacuoles become greater, the fluid rushes in collapsing the vacuole very rapidly. This violent collapse, combined with the liquid jets velocity, provides an intense action in a minute area. This reaction exist throughout the reactor. |
