Large-eddy simulations (LESs) of cryogenic nitrogen injection into a warm environment at
supercritical pressure are performed and real-gas thermodynamics models and subgrid …

We derive and analyze a model for implicit Large Eddy Simulation (LES) of compressible
flows that is applicable to a broad range of Mach numbers and particularly efficient for LES …

Certain experiments in quasi-isobaric supercritical injection remain unexplained by the
current state of theory: Without developing a constant value potential core as expected from …

This paper introduces a new model for real gas thermodynamics, with improved accuracy,
performance, and robustness compared to state-of-the-art models. It is motivated by the …

Large-eddy simulations are carried out for the coaxial injection of liquid nitrogen and
preheated hydrogen at supercritical pressures. The conditions are similar to that in typical …

The modeling of trans-and supercritical mixing and combustion introduces considerable
challenges for predictive rocket combustion simulations. Near the critical point, the thermo …

A new era in spaceflight has begun. What used to be an endeavor of nations, is now
achieved by private companies. When the first man-made object, the A4 rocket, reached …

In a joint effort to develop a robust numerical tool for the simulation of injection, mixing, and
combustion in liquid rocket engines at high pressure, a real-gas thermodynamics model has …

This thesis gives a résumé of my work as an academic employee at the Institute of
Aerodynamics and Gas Dynamics (IAG) of the University of Stuttgart. I want to thank my …

The combustion chamber pressure of rockets, gas turbines and diesel engines is known to
be above the critical pressure of fuel and oxidizers. In the case of rocket engines the fuel …
