Nonlinear Dynamics of Capacitive Charging and Desalination by Porous Electrodes

, 2009
The rapid and efficient exchange of ions between porous electrodes and aqueous solutions is important in many applications, such as electrical energy storage by super-capacitors, water desalination and purification by capacitive deionization (or ...

Emergence of stochastic dynamics in plane Couette flow [PDF]

, 2016
Spatially localized states play an important role in transition to turbulence in shear flows (Kawahara, Uhlmann & van Veen, Annu. Rev. Fluid Mech. 44, 203 (2012)).

How does flow in a pipe become turbulent?

, 2007
The transition to turbulence in pipe flow does not follow the scenario familiar from Rayleigh-Benard or Taylor-Couette flow since the laminar profile is stable against infinitesimal perturbations for all Reynolds numbers.

Asymptotics for moist deep convection I: refined scalings and self-sustaining updrafts [PDF]

Theoretical and Computational Fluid Dynamics, 2017
Moist processes are among the most important drivers of atmospheric dynamics, and scale analysis and asymptotics are cornerstones of theoretical meteorology.

An incompressible 2D didactic model with singularity and explicit solutions of the 2D Boussinesq equations

, 2014
We give an example of a well posed, finite energy, 2D incompressible active scalar equation with the same scaling as the surface quasi-geostrophic equation and prove that it can produce finite time singularities. In spite of its simplicity, this seems to

Fluctuation-enhanced electric conductivity in electrolyte solutions

, 2017
In this letter we analyze the effects of an externally applied electric field on thermal fluctuations for a fluid containing charged species. We show in particular that the fluctuating Poisson-Nernst-Planck equations for charged multispecies diffusion ...

Dynamics of Three Vortices in a Two-Layer Rotating Fluid

, 2004
The problem of studying the motion of three vortex lines with arbitrary intensities in an unbounded two-dimensional finite-thickness layer of a homogeneous fluid is known to belong to the class of integrable problems.

Vortices within vortices: hierarchical nature of vortex tubes in turbulence

, 2013
The JHU turbulence database [1] can be used with a state of the art visualisation tool [2] to generate high quality fluid dynamics videos. In this work we investigate the classical idea that smaller structures in turbulent flows, while engaged in their ...

Spatiotemporally Mapped Endothelial Dysfunction at Bifurcations in a Coronary Artery‐on‐a‐Chip

Advanced Materials & Technologies
Atherosclerotic plaques are commonly observed at low shear regions, in particular, the left main coronary artery (LMCA) bifurcation. Low shear regions at bifurcations promote endothelial dysfunction, a key factor initiating atherogenesis, however ...
