Transport coefficients for electrolytes in arbitrarily shaped nano and micro-fluidic channels
N. A. Mortensen, L. H. Olesen, H. Bruus
We consider laminar flow of incompressible electrolytes in long, straight channels driven by pressure and electro-osmosis. We use a Hilbert space eigenfunction expansion to address…
Universal dynamics in the onset of a Hagen-Poiseuille flow
Niels Asger Mortensen, Henrik Bruus
The dynamics in the onset of a Hagen-Poiseuille flow of an incompressible liquid in a channel of circular cross section is well-studied theoretically. We use an eigenfunction expan…
Universality in edge-source diffusion dynamics
N. A. Mortensen, F. Okkels, H. Bruus
We show that in edge-source diffusion dynamics the integrated concentration N(t) has a universal dependence with a characteristic time-scale tau=(A/P)^2 pi/(4D), where D is the dif…
Particle motion in microfluidics simulated using a Femlab implementation of the level set method
Martin Heller, Henrik Bruus
We implement the level set method for numerical simulation of the motion of a suspended particle convected by the fluid flow in a microchannel. The method automatically cope with t…
Microfluidic capturing-dynamics of paramagnetic bead suspensions
Christian Mikkelsen, Henrik Bruus
We study theoretically the capturing of paramagnetic beads by a magnetic field gradient in a microfluidic channel treating the beads as a continuum. Bead motion is affected by both…
