摘要：

To compare the performances of three power ultrasonic devices at 20 kHz: a horn, a cup horn and a tube, the local intensity distributions of local effects of cavitation have been investigated. The sensor is an electrochemical probe, measuring the solid-liquid mass transfer rate, related to the cavitation intensity. The axial and radial profiles of mass transfer coefficients have been investigated in three devices, at various power inputs. In all these equipments very strong heterogeneities have been characterized, whether a standing wave appears or not. (C) 1998 Elsevier Science B.V. All rights reserved.
