ABSTRACT
We developed a method to actuate oscillation of a sessile bubble in a fluid to produce steady streaming within the fluid. This method is based on time-periodic control of the wettability of the bubble by electrowetting. Jet velocity is proportional to oscillation amplitude and is greatest at natural oscillation frequencies. Analytical and numerical analyses indicate that the jet is produced by steady streaming in the Stokes layer.

The linear stability of superposed layers of viscous, immiscible fluids of different densities subject to horizontal oscillations, is analyzed with a spectral collocation method and Floquet theory. We focus on counterflowing layers, which arise when the horizontal volume-flux is conserved,...

For the conditions of thin-slab continuous casting, air-mist secondary cooling occurs in the transition-boiling regime, possibly as a result of an enhanced intermittent contact of high- momentum water drops with the hot metallic surface. The dynamics of the intermittent contact or...
