Marcus Grünewald - Mechanical Engineering

Thermo- and Fluiddynamics

Laboratory for Fluid Separation

Research Area

At the laboratory for fluid separations, we are working on different research areas: absorption and multiphase flows, reaction engineering, process design and flexible apparatuses. In all research areas, we are focusing on the implementation of new measurement techniques to acquire different state variables or hydrodynamic phenomena within the apparatuses. Where possible we combine experimental measurement techniques with multidimensional modelling and new evaluation methodologies. We have a chemical lab as well as a larger facility to perform experiments in our technical columns. For example, we are using a fiber optic temperature measurement system to acquire the temperature profiles within tube reactors for heterogeneously catalyzed gas phase reactions. Combining experimental results with continuous reactor models give us a further insight in heat transport effects within the reactors. In another example regarding multiphase gas-liquid systems, we are using a wire mesh sensor to get insight in the phase distribution in the cross sections. Together with adequate models, we develop methodologies to improve the scale-up.

Candidate Profile

Doctoral degree in chemical engineering, process engineering or technical chemistry. Experience in mathematical modelling as well as dynamic and steady state simulation of process equipment. Experience in performing experiments in the lab involving process equipment. Basic knowledge in process design. Interest in aspects regarding the shift from fossil energy and resource feedstock to the use of renewable energies and bio-based resources in chemical processes and the investigation of associated questions.

Jeanette Hussong - Mechanical Engineering

Thermo- and Fluiddynamics

Research Team Laser Measurement Techniques in Multiphase Flows (Fluiddynamics)

Research Area

The Research Group of Laser Measurement Techniques in Multiphase Flows investigates the scale-resolved multiphase dynamics of cavitating flows, suspension flows and porous media flow. For this, non-invasive optical laser measurement techniques such as Micro-PIV, A-PTV, Interferometry and Shadowgraphy are adapted or combined to study hydrodynamic particle dynamics and migration effects in semi-dilute suspensions, cavitation induced pressure wave dynamics, flows in microfluidic chips or turbulent flows through packed beds and porous interfaces. Our research aims to understand basic fluid-dynamical phenomena and to characterise novel fluiddynamical systems utilizing non-invasive laser measurement techniques.

Candidate Profile

The candidate needs to have a very strong background in fluiddynamics. We are seeking to combine in each research topic numerical and experimental studies. The candidate should aim to use the two weeks stay to collect ideas and prepare a project proposal for a longer term funding in our research group. We are looking for candidates that like to work in the field of fluid dynamics with either experimental or numerical focus that is related to our research topics.
