Research interests

Coming from general computational engineering I focused during the last years on mathematical modeling in the context of multiphase flows, especially liquid/gas systems. Thereby are my main interests in the different mechanisms of mass transport, i.e. convection, diffusion and migration. Aiming at an increased understanding of complex phenomena I am developing and analysing Interface Tracking Methods suitable for Direct Numerical Simulation of rising bubbles.

Beeing a fan of free software I am doing my studies within the framework provided by OpenFOAM Extend, especially by extending the therein contained top level solvers interTrackFoam and bubbleInterTrackFoam.

Research topic

Trying to put everything I am working on into a descriptive title is rather difficult. However, the official topic of my thesis is Modeling and Numerical Simulation of Multi-Component Two-Phase Fluid Systems with Ionic Species. Please visit the webpage of my research project to read more.

Bachelor Thesis/Master Thesis/ADP

While working on my PhD project frequently questions arise that are perfectly suited for a bachelor or master thesis. If you would like to use your thesis to make your own contribution to the research field of multiphase flows, please do not hesitate to contact me.
