Electroosmotic flow in small-scale channels induced by surface-acoustic waves
Mathias Dietzel, Steffen Hardt
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…
Optimized thermoelectric sensitivity measurement for differential thermometry with thermopiles
Tim Prangemeier, Iman Nejati, Andreas Müller +3
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 t…
Energy conversion by surface-tension driven charge separation
Cesare Pini, Tobias Baier, Mathias Dietzel
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…
Conjugated liquid layers driven by the short-wavelength Bénard-Marangoni instability: experiment and numerical simulation
Iman Nejati, Mathias Dietzel, Steffen Hardt
The coupled dynamics of two conjugated liquid layers of disparate thicknesses, which coat a solid substrate and are subjected to a transverse temperature gradient, is investigated.…
Interfacial instability of liquid films coating the walls of a parallel-plate channel and sheared by a gas flow
Miklós Vécsei, Mathias Dietzel, Steffen Hardt
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…
Thermoelectricity in confined liquid electrolytes
Mathias Dietzel, Steffen Hardt
The electric field in an extended phase of a liquid electrolyte exposed to a temperature gradient is attributed to different thermophoretic mobilities of the ion species. As shown…
