It
is well-known that the zone of effective erosion of power ultrasonic radiators
is no more than 40 mm width. The subject of this investigation is the
possibility of creation of strong cavitation outside this zone, e.g. at the
distance up to 150 mm from the radiator. The effect is provided by application
of low-amplitude ultrasonic vibrations from the second radiator with power not
exceeding 10% of the high-amplitude radiator. This effect is proved by
experiments and realized in scale models of ultrasonic cleaning equipment.
