Researchers at Tohoku University are developing a method to improve the aggressive intensity of cavitation without the need to increase the input power.
Cavitation - the formation, growth and subsequent collapse of microbubbles - produces high, localized energy which can be used in chemical processes for treating water and the pretreatment of biomass.
The research team found that the conventional cavitation method of applying ultrasonic energy was not strong enough, so they proposed using hydrodynamic cavitation instead.
