A Lattice Boltzmann study of flow along patterned surfaces and through channels with alternating slip length
Nayaz Khalid Ahmed, Martin Hecht
In microfluidics, varying wetting properties, expressed in terms of the local slip length, can be used to influence the flow of a liquid through a device. We study flow past surfac…
A boundary condition with adjustable slip length for Lattice Boltzmann simulations
Nayaz Khalid Ahmed, Martin Hecht
A velocity boundary condition for the Lattice Boltzmann simulation technique has been proposed recently by Hecht and Harting[arxiv:0811.4593]. This boundary condition is independen…
Agglomeration and filtration of colloidal suspensions with DVLO interactions in simulation and experiment
Bastian Schaefer, Martin Hecht, Jens Harting +1
Cake filtration is a widely used solid-liquid separation process. However, the high flow resistance of the nanoporous filter cake lowers the efficiency of the process significantly…
Implementation of on-site velocity boundary conditions for D3Q19 lattice Boltzmann
Martin Hecht, Jens Harting
On-site boundary conditions are often desired for lattice Boltzmann simulations of fluid flow in complex geometries such as porous media or microfluidic devices. The possibility to…
Computational Steering of Cluster Formation in Brownian Suspensions
Martin Hecht, Jens Harting
We simulate cluster formation of model colloidal particles interacting via DLVO (Derjaguin, Landau, Vervey, Overbeek) potentials. The interaction potentials can be related to exper…
Formation and growth of clusters in colloidal suspensions
Martin Hecht, Jens Harting, Hans J. Herrmann
Depending on the pH value and salt concentration of Al2O3 suspensions different microstructures can form. Especially the clustered one is of major interest for industrial purposes…
