| Abstract(in English) | Development of acoustic streaming generated in water with 5.05-MHz cw ultrasound transmitted from a flat disk transducer has been measured using a laser Doppler velocimeter. The streaming forms an accelerating flow in the direction of sound propagation and it turns turbulent at a distance if the source sound amplitude is large. The transition point approaches the transducer as the source amplitude increases. The turbulence in the axial component of the streaming velocity is larger than that in the radial component and it contains fluctuations of period of several seconds to several minutes. The build-up process of streaming velocity after the ultrasound is switched on is monotonous as long as the source amplitude is small. When the amplitude increases, there appears anomalous plateaus and humps which take the same form even if experimental conditions are changed. |
