Numerical Simulation And Control Of Thermocapillary Convection In Cavities And Liquid Layers
… thermocapillary convection in cavities and liquid layers in the absence of gravity is studied. The flow is driven by a temperature gradient parallel to the interface.;An effective algorithm for analysis of the above problem has been developed. The algorithm is based on a coordinate …

Stability analysis of gravity-driven viscosity-stratified coating flows
… in covering a planar surface with one or more liquid layers. The challenging stability analysis of a coating flow on a curved substrate surface is discussed. The mathematical foundation on which to analyse the stability of this inherently spatial coating flow problem is provided by a Green's …

Non-linear, non-spherical bubble dynamics near a two fluid interface
… incompressible fluid dynamics of the exterior liquid layers, based on a boundary integral implementation coupled with the vortex ring toroidal bubble model [53]. The transition through the null impulse state has been investigated, demonstrating excellent agreement with the water/white spirit …

Microcell fabrication and resolution enhancement for in situ liquid cell electron microscopy
Liquid cell electron microscopy has been proven to provide high spatial and temporal resolution for studying liquid layers and the solid-liquid interface at the micro and nano scale. The in situ environment allows for spatial and spectral characterization and quantification of the dynamics and …

One-dimensional numerical model for evaporation and oxidation of hydrocarbon fuels
… aspects of evaporation and oxidation of a thin liquid fuel layer exposed to an incoming premixed flame. In particular, the model is applied to predict the total evaporation and ensuing oxidation of a liquid layer under repeated cycles. Methanol was used as a baseline fuel. Simplifications in the …

Renewable energy supply and storage: liquid metal battery stability
Liquid metal batteries (LMBs) offer a new opportunity for large-scale electrical energy storage. The three liquid layer self-segregated structure of the battery provides a number of advantages in comparison to classical batteries: fast kinetics, long lifetime, large current densities, easy …

Ultrafast photo-acoustic spectroscopy of super-cooled liquids
… longitudinal and transverse acoustic waves in liquids at gigahertz frequencies. The experimental effort was designed for the study of supercooled liquids whose slower relaxation dynamics extend to gigahertz frequencies at high temperatures and whose faster dynamics are centered uniquely in the …

Stability analysis of a bilayer contained within a cylindrical tube
Airways in the lung are coated with a liquid bilayer consisting of a serous layer adjacent to a more viscous mucus layer which is contiguous with the air core. An instability due to surface tension at the interfaces may lead to the formation of a liquid plug that blocks the passage of air. This is …

Intensification of Gas Absorption in a Downward Flow Microbubble Bioreactor
… rate via rapid delivery of gas feedstock to the liquid phase which in turn requires a high volumetric mass transfer rate (). One strategy to achieve this goal is to increase interfacial area density, <em>a</em>, to >3000 m<sup>2</sup> m<sup>-3</sup>, while minimizing use of energy. Here we show a …
