摘要: Acoustic streaming, which is induced in an open channel by a cylindrical exciter vibrating at 30kHz, experimentally investigated using particle imaging velocimetry. Induced streaming pattern and velocity field for the gap of 18mm are presented. The symmetric distinctive steady rotational flow with local eddies observed. maximum measured stands 0.16cm∕s vibration amplitude 50μm excitation frequency 30kHz.
