Spreading of viscoplastic droplets
نویسندگان
چکیده
The spreading under surface tension and gravity of a droplet yield-stress fluid over thin film the same material is studied. converges to final equilibrium shape once driving stresses inside fall below yield stress. Scaling laws are presented for radius complemented with an asymptotic analysis shallow droplets. Moreover, numerical simulations using volume-of-fluid method regularized constitutive law, experiments aqueous solution Carbopol presented.

The spreading of macroscopic droplets
2014 Some experimental results on the macroscopic spreading of hanging and sessile drops on smooth surfaces are presented. The results for sessile drops nicely corroborate the main aspects of the spreading theory of de Gennes and Joanny. However, it is shown that one assumption of the theory, namely the retainment of a self-similar shape during spreading, which is approximately true for sessile...
متن کاملDefect modeling in spreading nematic droplets.
Experiments by Poulard and Cazabat [Langmuir 21, 6270 (2005)] on spreading droplets of nematic liquid crystal (NLC) reveal a surprisingly rich variety of behavior, including at least two different emerging length scales resulting from a contact line instability. In earlier work [Cummings, Lin, and Kondic, Phys. Fluids 23, 043102 (2011)] we modified a lubrication model for NLCs due to Ben Amar a...
متن کاملInstabilities in droplets spreading on gels.
We report a novel surface-tension driven instability observed for droplets spreading on a compliant substrate. When a droplet is released on the surface of an agar gel, it forms arms or cracks when the ratio of surface-tension gradient to gel strength is sufficiently large. We explore a range of gel strengths and droplet surface tensions and find that the onset of the instability and the number...
متن کاملRe-examination of complete spreading of polydimethylsiloxane droplets
The motion of the three-phase line created by a liquid droplet on a flat solid substrate has been extensively studied for more than a century, yet the constitutive relation governing this motion remains unclear. When a liquid droplet is placed in contact with a flat substrate, the system is driven towards equilibrium. The contact angle relaxes from its initial value at the moment of contact, to...
متن کاملFast evaporation of spreading droplets of colloidal suspensions.
When a coffee droplet dries on a countertop, a dark ring of coffee solute is left behind, a phenomenon often referred to as the coffee-ring effect. A closely related yet less-well-explored phenomenon is the formation of a layer of particles, or skin, at the surface of the droplet during drying. In this work, we explore the behavior of a mathematical model that can qualitatively describe both ph...
