Simulations of slip flow on nanobubble-laden surfaces
Jari Hyväluoma, Christian Kunert, Jens Harting
On microstructured hydrophobic surfaces, geometrical patterns may lead to the appearance of a superhydrophobic state, where gas bubbles at the surface can have a strong impact on t…
Lattice Boltzmann simulations of liquid flilm drainage between smooth surfaces
Christian Kunert, Jens Harting
Exploring the hydrodynamic boundary of a surface by approaching a colloidal sphere and measuring the occurring drag force is a common experimental technique. However, numerous para…
Random-roughness hydrodynamic boundary conditions
Christian Kunert, Jens Harting, Olga I. Vinogradova
We report results of lattice Boltzmann simulations of a high-speed drainage of liquid films squeezed between a smooth sphere and a randomly rough plane. A significant decrease in t…
Lattice Boltzmann simulations in microfluidics: probing the no-slip boundary condition in hydrophobic, rough, and surface nanobubble laden microchannels
Jens Harting, Christian Kunert, Jari Hyväluoma
In this contribution we review recent efforts on investigations of the effect of (apparent) boundary slip by utilizing lattice Boltzmann simulations. We demonstrate the applicabili…
Simulation of fluid flow in hydrophobic rough microchannels
Christian Kunert, Jens Harting
Surface effects become important in microfluidic setups because the surface to volume ratio becomes large. In such setups the surface roughness is not any longer small compared to…
Roughness induced boundary slip in microchannel flows
Christian Kunert, Jens Harting
Surface roughness becomes relevant if typical length scales of the system are comparable to the scale of the variations as it is the case in microfluidic setups. Here, an apparent…
