METHOD OF GENERATION OF ULTRASONIC WAVES IN LIQUID FLOW Russian patent published in 1997 - IPC

FIELD: ultrasonic generators. SUBSTANCE: steam flow is fed into liquid film, whose temperature is below the steam condensation point. Film flow of liquid is provided by action of the field of centrifugal forces on it. Prior to introduction to liquid, the steam flow is subjected to adiabatic expansion. Pulsating steam feed may be accomplished at a supersonic outflow velocity. EFFECT: enhanced power intensity of generated waves. 3 cl
