Characterization of the Ultrasound Activity in a Liquid Flow Using Particles Images Velocimetry (PIV) and Electrochemical Mass Transfer Measurements

Résumé

The present work is dedicated on the interactions between a liquid circulation and a perpendicular acoustic wave propagation. A specific experimental setup enables us to study one transducer operating at 20kHz, with the help of electrochemical mass transfer measurements combined with Particles Images Velocimetry (PIV) determination. Electrodes were located on the wall opposite to the acoustic emission. Experiments were performed for various Reynolds numbers: from 0 to 50 000 (different liquid flow rates and viscosities). Both PIV and electrochemical measurements methods were found to be relevant, and had delivered complementary information. Even if PIV showed that the plume due to streaming was highly deflected by the additional flow, electrochemical measurements showed that there was still an activity, higher than in silent conditions, on the wall facing the transducer. Thus the ultrasound contribution remained noticeable on the surface opposite to the transducer even for a disturbed hydrodynamic environment due to the presence of a liquid circulation perpendicular to the wave propagation.
