Numerical simulations of the Navier-Stokes, Nernst-Planck, and the Poisson equations are employed to describe the transport processes in an aqueous electrolyte in a parallel-plate nanochannel, where surface-acoustic waves (SAWs) are standing or trave

The Lattice-Boltzmann-Method (LBM) is a powerful and robust approach for calculating fluid flows over or through complex geometries. This method was further developed for allowing the calculation of several problems relevant to dispersed particle-lad

The stability of liquid films coating the walls of a parallel-plate channel and sheared by a pressure-driven gas flow along the channel centre is studied. The films are susceptible to a long-wavelength instability, whose dynamic behaviour is found -

A novel approach to calibrate the sensitivity of a differential thermometer, consisting of several thermocouples connected in series (thermopile), has been developed. The goal of this method is to increase the accuracy of small temperature difference

Agglomerated particles appear in various areas of process industry in the form of products, waste or contamination. In this work, the Lattice–Boltzmann Method (LBM) is used to perform high resolution simulations for investigating forces on agglomer

The main purpose of this contribution is to present a lattice Boltzmann method for modelling the transport, collision and agglomeration of freely moving spherical particles and agglomerates. In order to take the hydrodynamic interaction between fluid

In this work a numerical approach to predict the deposition behaviour of nano-scale particles on the surface of a single fibre by resolving the resulting dendrite-like particle structures in detail is presented. The gas flow simulation is carried out

In spray freeze drying (SFD) solutions are frozen by spraying into a very cold environment and subsequently dried by sublimation. In contrast to conventional freeze drying, spray freeze drying has the possibility to produce flowable lyophilizates whi
In this work, the shear-induced electrokinetic streaming potential present in free-surface electrolytic flows subjected to a gradient in surface tension is assessed. Firstly, for a Couette flow with fully resolved electric double layer (EDL), the str

In this work, a gas-particle flow over a structured sensor surface is numerically investigated. A system of parallel electrodes with an applied voltage is distributed on top of a nonconducting flat surface. The considered submicron particles (size ra
