TL;DR: It is shown that the novel streaming force approach is a valid approximation for the simulation of the acoustic streaming induced fluid flow, allowing a rapid and simple estimation of the flow field of SAW based microfluidic devices.

TL;DR: In this article, the authors investigated the thermocapillary effect on hydrogen bubbles evolving at microelectrodes and found significant Ohmic heating near the micro-electrode and a strong flow driven along the interface away from the micro electrode.

TL;DR: In this paper, a measurement technique is introduced, that relates the luminescent intensity ratio of individual dual-color luminecent tracer particles to temperature, and different processing algorithms are tested on synthetic particle images and compared with respect to their accuracy in estimating the intensity ratio.

TL;DR: In this article, a novel optical measurement technique is introduced and qualified which enables the simultaneous determination of the three-dimensional temperature field and the three components of the 3D velocity field in microfluidic applications with only one camera.

TL;DR: In this paper, an alternative explanation for the observed bubble behavior is suggested: it might result from the comparatively strong global flow generated by the additive effect of a group of bubbles, and the experimental and numerical results obtained in this paper demonstrate that this pressure decrease is too weak as to effectively change the detachment process.
