Abstract

Acoustic streaming (AS) is a steady fluid flow driven by the absorption ofhigh amplitude ultrasonic vibrations due to the nonlinear effect. With potentialapplications in micro-pumping, the AS-related behaviors remain as interestingtopics to the acoustic community. Anti-symmetric flexural (ASF) modes are wedgewaves with their particle motion anti-symmetric about the apex mid-plane. Withthe energy tightly confined near the wedge-tip, ASF mode has relatively highacoustic amplitude which suggest it's as a good candidate for the investigationof AS. In this study, the AS behaviors induced by ASF modes are investigated bycomputational fluid dynamics (CFD). The ASF induced three-dimensional AS flowfield are presented through the CFD analysis.
