A model is presented for the solution of electrokinetic phenomena of colloidal suspensions in fluid mixtures. We solve the discrete Boltzmann equation with a BGK collision operator using the lattice Boltzmann method to simulate binary fluid flows. So

Direct simulation of liquid–gas–solid flow with a free surface lattice Boltzmann method

Autor: Ulrich Rüde, Simon Bogner, Jdr Jens Harting

Publikováno v: International Journal of Computational Fluid Dynamics, 31(10), 463-475. Taylor and Francis Ltd.

Direct numerical simulation of liquid-gas-solid flows is uncommon due to the considerable computational cost. As the grid spacing is determined by the smallest involved length scale, large grid sizes become necessary -- in particular if the bubble-pa

Computer Physics Communications, 189, 92-98. Elsevier

We discuss two topics that we have encountered in our lattice-Boltzmann simulations of complex fluids: the sizes of droplets in particle-stabilised emulsions and deformable particles in fluid flow. The common factor in these seemingly disparate subje

Dynamic wetting : status and prospective of single particle based experiments and simulations

Publikováno v: New Biotechnology, 32(5), 420-432. Elsevier

The fundamental molecular and microscopic properties of materials leading to dynamic wetting and relaxation effects have been subject to numerous studies in the past decades, but a thorough understanding is still missing. While most previous experime

Direct assembly of magnetic Janus particles at a droplet interface

Publikováno v: ACS Nano, 11(11), 11232-11239. American Chemical Society

Self-assembly of nanoparticles at fluid-fluid interfaces is a promising route to fabricate functional materials from the bottom-up. However, directing and controlling particles into highly tunable and predictable structures -- while essential -- is a

Inertial focusing of finite-size particles in microchannels

Journal of fluid mechanics 840, 613-630 (2018). doi:10.1017/jfm.2018.95

At finite Reynolds numbers, Re, particles migrate across laminar flow streamlines to their equilibrium positions in microchannels. This migration is attributed to a lift force, and the balance between this lift and gravity determines the location of

In this work we consider the following question: given a mechanical microswimming mechanism, does increased deformability of the swimmer body hinder or promote the motility of the swimmer? To answer this we run immersed-boundary-lattice-Boltzmann sim

A substantial number of algorithms exists for the simulation of moving particles suspended in fluids. However, finding the best method to address a particular physical problem is often highly non-trivial and depends on the properties of the particles

Timescales of emulsion formation caused by anisotropic particles

Autor: FS Florian Günther, Scj Stefan Frijters, Jdr Jens Harting

Publikováno v: Soft Matter, 10(27), 4977-4989. Royal Society of Chemistry

Particle stabilized emulsions have received an enormous interest in the recent past, but our understanding of the dynamics of emulsion formation is still limited. For simple spherical particles, the time dependent growth of fluid domains is dominated
