Welcome to my research website, which is centered around my work on high-pressure thermofluids and supercritical propulsion analysis and modeling. If you want to get in touch, please send me an email!


For an introduction to "High-pressure transcritical atomization and combustion", here is a video of my tutorial, held during the 16th Biennial Summer Program (2016) of the Center for Turbulence Research at Stanford University.

Supercritical fluids

The main focus of my research is the analysis and numerical modeling of fluid behavior at high pressures. While 'supercritical fluids' may sound like a very specialized niche topic, it is actually not: Supercritical fluids are ubiquitous and can be found e.g. in Diesel engines, gas turbines, and liquid propellant rocket engines. Supercritical fluids cool power plants, and serve as working fluids in supercritical power cycles. Extraction of oil and CO2 sequestration are supercritical fluids processes. Finally, supercritical fluids can be found in nature, forming the atmosphere of planets like Venus or Jupiter.

The main challenge in modeling and understanding is the thermodynamic behavior at high pressures: neither liquid nor perfect gas idealizations remain applicable. Instead, fluid state behavior is governed by real fluid equations of state (such as Peng-Robinson, Redlich-Kwong, etc.), and mixing rules.

The goal of my research is to drive the understanding of high pressure thermodynamics to advance modeling and technical solutions for real world problems.

Key results


A first quantitative analysis of heating processes at supercritical pressure reveals that there is a supercritical transition akin to subcritical vaporization - pseudoboiling. This is important for the design and interpretation of experimental and numerical test cases. [more]

Thermal jet break-up

The pseudo-boiling phenomenon causes a very strong temperature sensitivity during injection. This gives rise to a thermal break-up mechanism - in addition to classical mechanical atomization. [more]


For high pressure diffusion flames it can be shown that mixing occurs merely between ideal gases, without the influence of any real gas effects. Multi-fluid-mixing is a new thermodynamic model that uses this to allow application of high quality equations of state without additional computational cost. [more]




I am currently a Postdoctoral Fellow at the Center of Turbulence Research at Stanford University, where I am studying the application of chemical engineering methods and data analysis of molecular dynamics simulations on high pressure fluid behavior and modeling. Technical processes of interest range form fuel injection to CO2 sequestration.

Before, I have been a Research Associate at the German Aerospace Center (DLR), Institute of Aerodynamics and Flow Technology, Spacecraft Department in Göttingen, where I did research on combustion and injection in rocket engines, hydrazine thrusters, and hypersonic flow / flow control using energy deposition.

I received my Dr.-Ing. (PhD) degree from the University of Stuttgart (Dissertation) and the Dipl.-Ing. (MSc) from RWTH Aachen University in Germany. While studying for the MSc, I had the opportunity to spend a year as a Graduate Research Trainee at the University of Tennessee Space Institute.

My specialization is Computational Fluid Dynamics, both as a developer and analyst, with particular emphasis on reactive flow in combustion systems.
