Upcoming

November 22, 2016, Portland, OR: I will give a talk at this year's 69th Annual Meeting of the APS Division of Fluid Dynamics about "The latent heat of vaporization of supercritical fluids", co-authored by M. Raju, J.-P. Hickey and M. Ihme. Room: E145, 3:01 PM - 3:14 PM.

January 11, 2017, Grapevine, TX: I am looking forward to discuss "Seven questions about supercritical fluids - towards a new fluid state diagram" at the AIAA SciTec conference 2017, co-authered by M. Raju, P.C. Ma, J.-P. Hickey, and M. Ihme. Room: San Antonio 6, 11:00 AM - 11:30 AM.

Research Interest

The main focus of my research is the analysis and numerical modeling of high pressure injection and combustion. These phenomena are technically ubiquitous, and can be found e.g. in liquid propellant rocket engines, Diesel engines, and gas turbines.

The main challenge 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

Pseudoboiling

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]

Multi-fluid-mixing

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]

About

I am currently a Postdoctoral Fellow at the Center of Turbulence Research at Stanford University, focusing on high pressure injection phenomena and modeling.

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.
