Large Eddy Simulation of Jets Laden with Evaporating Drops
LES of a circular jet laden with evaporating liquid drops are conducted t o assess computational-drop modeling and three different SGS-flux models: the Scale Similarity model (SSC), using a constant coefficient calibrated on a temporal mixing layer DNS database, and dynamic-coefficient Gradient and Smagorinsky models (GRD and SMD, respectively). The GRD model was used for LES of an unforced jet...
متن کاملAutophobic Pinning of Drops of Alkanethiols on Goldl
This paper establishes conditions necessary for autophobic pinning of solutions of alkanethiols by their reaction *ith a gold surface. Interfacial tension and the kinetics of organizationof the SAMs are important considerations in the design of systems that limit the spread of drops across a surface that is reactive toward those drops. The iwo syite-s investigated in this paper-hexadecanethiol ...
متن کامل"Self-Shaping" of Multicomponent Drops.
In our recent study we showed that single-component emulsion drops, stabilized by proper surfactants, can spontaneously break symmetry and transform into various polygonal shapes during cooling [ Denkov Nature 2015 , 528 , 392 - 395 ]. This process involves the formation of a plastic rotator phase of self-assembled oil molecules beneath the drop surface. The plastic phase spontaneously forms a ...
متن کاملEngineered cell-laden human protein-based elastomer.
Elastic tissue equivalence is a vital requirement of synthetic materials proposed for many resilient, soft tissue engineering applications. Here we present a bioelastomer made from tropoelastin, the human protein that naturally facilitates elasticity and cell interactions in all elastic tissues. We combined this protein's innate versatility with fast non-toxic fabrication techniques to make hig...
متن کاملSelf-Pinning on a Liquid Surface.
We report on the first experimental evidence of a self-pinning liquid drop on a liquid surface. This particular regime is observed for a miscible heavier oil drop (dichloromethane) deposited on an aqueous solution laden by an ionic surfactant (hexadecyltrimethylammonium bromide). Experimental characterization of the drop shape evolution coupled to particle image velocimetry points to the correl...
