Electrodeformation of vesicles suspended in a liquid medium

Wed, 10/24/2018 - 11:00

Author(s): Adnan Morshed, Prashanta Dutta, Mohammad Robiul Hossan, and Robert Dillon

The electrodeformation of a bio-vesicle suspended in liquid media depends on the conductivity ratio of fluid and vesicle, applied electric field, membrane capacitive charging, and vesicle initial shape. Our theoretical study provides important insights on this complex fluid-structure interaction.

Stokes' second problem and reduction of inertia in active fluids

Mon, 10/22/2018 - 11:00

Author(s): Jonasz Słomka, Alex Townsend, and Jörn Dunkel

Simulations predict that a pendulum immersed in an active fluid oscillates faster than in a passive fluid due to a reduction of the fluid inertia. The decrease in inertia is mediated by topological defects in the stress field, which can effectively decouple the bulk flow dynamics from the pendulum.

Jump-to-contact instability: The nanoscale mechanism of droplet coalescence in air

Fri, 10/19/2018 - 11:00

Author(s): Véronique Chireux, Matthieu Protat, Frédéric Risso, Thierry Ondarçuhu, and Philippe Tordjeman

Atomic Force Microscope observations find that two drops of radii 0.7 to 70 micrometers jump to contact when separated by a distance that scales as (HReq/γ)1/3 for small drops and as (H/γ)1/2 for larger drops.

Electrokinetics of a particle attached to a fluid interface: Electrophoretic mobility and interfacial deformation

Fri, 10/19/2018 - 11:00

Author(s): Michael Eigenbrod, Florian Bihler, and Steffen Hardt

The electrophoretic mobility of a particle at the interface between two fluids is computed. For thin Debye layers, the Smoluchowki mobility is recovered. Generally, the mobility depends on the contact angle between the fluids and the particle. The interfacial deformation is also calculated.

Plastron morphology and drag of a superhydrophobic surface in turbulent regime

Thu, 10/18/2018 - 11:00

Author(s): D. Reholon and S. Ghaemi

We perform drag force and particle tracking velocimetry measurements on a body-of-revolution coated with a superhydrophobic layer for Re between 5×105 and 1.5×106. As Re increases, drag reduction decreases, and a full plastron becomes isolated air bubbles as thin menisci.

Helicity in superfluids: Existence and the classical limit

Thu, 10/18/2018 - 11:00

Author(s): Hridesh Kedia, Dustin Kleckner, Martin W. Scheeler, and William T. M. Irvine

The analog of hydrodynamic helicity in superfluids is zero for all flows. A semiclassical limit is found in the link and writhe of bundles of superfluid vortices. Numerical simulations show that the dynamics of semiclassical helicity closely resemble those seen in experiments in viscous fluids.

Orthogonal and antiparallel vortex tubes and energy cascades in quantum turbulence

Wed, 10/17/2018 - 11:00

Author(s): Tsuyoshi Kadokura and Hiroki Saito

Numerical simulations of the Gross-Pitaevskii equation reveal that parent and child vortices tend to be orthogonal to each other in quantum turbulence. This is a manifestation of the energy cascades and may be responsible for Kolmogorov’s law in superfluids.

Mixing layer instability and vorticity amplification in a creeping viscoelastic flow

Tue, 10/16/2018 - 11:00

Author(s): Atul Varshney and Victor Steinberg

In channel flow hindered by two widely spaced obstacles, an elastic instability of the mixing layer arises near an inflection point on nonuniform shear velocity profiles, resulting in intermittent small vortices. In elastic turbulence a growth in the averaged vorticity above the transition is found.
