Abstract

Microbubbles exposed to a sufficiently strong ultrasound field can show nonspherical oscillations called surface modes. In the vicinity of the bubble surface, these oscillations induce a slow mean flow named microstreaming. Microstreaming plays an important role in medical applications such as sonoporation as well as in engineering applications such as micromixing. A better understanding of the induced flows will hence be beneficial to a large number of applications. Recent studies mainly report on microstreaming induced by bubbles resting on a solid boundary. The observation of microstreaming around a single, free bubble is challenging, because several experimental difficulties have to be overcome: Avoidance of translational instabilities, obtainment of a steady-state behavior maintaining surface modes, correct choice of tracer particles, and correlation between fast temporal bubble dynamics and relatively slow microstreaming. We present an experimental setup, that accomplishes the simultaneous visualiza...

自由非球振荡微泡诱导微流的实验研究
暴露在足够强的超声场下的微泡可以表现出称为表面模态的非球形振荡。在气泡表面附近,这些振荡引起一种缓慢的平均流动,称为微流。微流媒体在医学应用(如超声加工)和工程应用(如微混合)中发挥着重要作用。因此,对诱导流的更好理解将有利于大量的应用。最近的研究主要报道了气泡在固体边界上引起的微流现象。观察单个自由气泡周围的微流是具有挑战性的,因为必须克服几个实验困难:避免平移不稳定性,获得维持表面模式的稳态行为,正确选择示踪粒子,以及快速时间气泡动力学和相对缓慢微流之间的相关性。我们提出了一个实验装置,实现了同步可视化。
