Detaillierte Untersuchung des Stoffübergangs in Blasenströmungen

Paaschen, Tim-Oliver (Hannover : Universität, 1998)

[no abstract]
Devolatilization of polymers by diffusion and foaming

Gestring, Ingo; Mewes, Dieter (London : SAGE Publications Ltd., 2002)

Devolatilization is a key step in polymer processing. Low-molecular-weight components are removed from a polymeric system. The transport of these components takes place by diffusion to the polymer-vapor interface. This ...
Digital laser micro- and nanoprinting

Li, Qingfeng; Grojo, David; Alloncle, Anne-Patricia; Chichkov, Boris; Delaporte, Philippe (Berlin : De Gruyter, 2018)

Laser direct writing is a well-established ablation technology for high-resolution patterning of surfaces, and since the development of additive manufacturing, laser processes have also appeared very attractive for the ...
Elucidating the effect of mass transport resistances on hydrogen crossover and cell performance in PEM water electrolyzers by varying the cathode ionomer content

Trinke, P.; Keeley, G.P.; Carmo, M.; Bensmann, B.; Hanke-Rauschenbach, R. (Bristol : IOP Publishing Ltd., 2019)

An important challenge for polymer electrolyte membrane (PEM) water electrolysis is to reduce the permeation of the produced gases. This crossover affects the cell efficiency and causes safety issues. The crossover increases ...
Influence of the channel design on the heat and mass exchange of induction channel furnace

Baake, E.; Jakovics, A.; Pavlovs, S.; Kirpo, M. (Bingley : Emerald Group Publishing Ltd., 2011)

Purpose - The purpose of this paper is to present in-depth numerical modelling of heat and mass exchange in industrial induction channel furnace (ICF). Design/methodology/approach - The turbulent heat and mass exchange in ...
Model tests on the control behaviour of a test air supply system in open or closed-loop operation

De Buhr, L.; Fleige, H.; Seume, J. (Bristol : Institute of Physics Publishing, 2018)

The Leibniz Universität Hannover is currently establishing a new mechanical engineering campus which includes a new research building "Dynamics of Energy Conversion" (DEW). This building provides a large compressor station ...
Numerical and experimental study of liquid metal stirring by rotating permanent magnets

Dzelme, V.; Jakovics, A.; Vencels, J.; Köppen, D.; Baake, E. (Bristol : Institute of Physics Publishing, 2018)

In this work, we study liquid gallium stirring by rotating permanent magnets. We demonstrate possibility of easily creating different flow patterns by rotating permanent magnets, which can be industrially important for ...
Understanding electrical under- and overshoots in proton exchange membrane water electrolysis cells

Immerz, C.; Bensmann, B.; Trinke, P.; Suermann, M.; Hanke-Rauschenbach, R. (Bristol : IOP Publishing Ltd., 2019)

Ability of dynamic operation seems to be an important feature of proton exchange membrane water electrolyzers (PEMWE) to become a relevant part of the future energy system. However, only few fundamental analyzes of the ...
