| Popis: | International audience; The acoustic streaming is a second-order steady flow, which is superimposed on the dominant acoustic velocity. It is induced by thenonlinearities of the acoustic propagation. These non linear phenomena are present in oscillating flows and generally result in a efficiency degradation of thermoacoustic devices. In this paper an exploration of the acoustic velocity field by PIV enabled to highlight and quantify these secondary flows. The measurements performed in phase synchronisation and by scanning the temporal period give us information on streaming profiles and allow plotting the acoustic velocity over time. |
