Two Droplets interaction on substrate
نویسنده
چکیده
Dynamics of two droplets interactions on a substrate (droplet impact on a sessile droplet) are numerically investigated using OpenFOAM. The impact speed, location of the impacting droplet, viscosity and surface tension were varied in the numerical studies. We found that when the surface tension dominates the flow, the mass canter of two droplets moves to impacting droplet side. When the inertia dominates the flow, the mass centre moves to the opposite direction.

Droplet actuation induced by coalescence: experimental evidences and phenomenological modeling
This paper considers the interaction between two droplets placed on a substrate in immediate vicinity. We show here that when the two droplets are of different fluids and especially when one of the droplet is highly volatile, a wealth of fascinating phenomena can be observed. In particular, the interaction may result in the actuation of the droplet system, i.e. its displacement over a finite le...
متن کاملMutual Electrostatic Interactions between Closely Spaced Charged Solder Droplets
Emerging technologies of net-form manufacturing and electronic packaging rely on the use of precisely deposited molten metal droplets with sizes on the order of 100 μm in diameter. In many technological realizations, closely spaced droplets are electrostatically charged and deflected onto a substrate in a manner similar to ink-jet printing in order to “print” fine features onto a board for elec...
متن کاملMorphological transitions of liquid droplets on circular surface domains.
We study morphological transitions of droplets on a structured substrate containing two circular lyophilic domains for arbitrary domain and substrate wettabilities. We derive the stability criterion that at least one of the droplets must be pinned at the domain boundary with a contact angle smaller than (pi)/(2). This determines seven classes of stable or metastable droplet morphologies of the ...
متن کاملEnergy and Second Law of Thermodynamics Analysis of Shower Cooling Tower with Variation in Inlet Air Temperature
A shower cooling tower (SCT) operates without fill because of salt decomposition on the fill that leads to deterioration of conventional cooling tower performance. This study presents a two-dimensional mathematical model for energy and exergy analysis of multi-diameter droplets and air interaction along with the height of the forced draft SCT, to predict the exit condition of water droplet for ...
متن کاملInterplay of Surface Energy and Bulk Thermodynamic Forces in Ordered Block Copolymer Droplets
The wetting state of a simple liquid on a solid substrate, as summarized by Young’s equation, is dictated by the interfacial energies of the different phases that coexist in the system. For simple fluids, rotational symmetry gives rise to symmetric droplets around the axis perpendicular to the substrate. This is not the case for nanostructured fluids, such as block copolymers, where the inheren...
