The injection of cryogenic fluids into environments where the prevailing conditions are
supercritical in comparison to the critical point of the injected cryogenic fluid is encountered …

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 …

This study focuses on the fundamental combustion instability issues in staged combustion
for liquid oxygen/kerosene rocket engines. A comprehensive and high-fidelity numerical …

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 …

While increased pressure and temperature contribute to an overall efficiency gain in the
mixing of propellants and oxidizers, characteristic of conditions in the combustion chambers …

Although OpenFOAM is a widely-used open source computational fluid dynamics (CFD)
tool, it is limited to numerical simulations of multi-dimensional reacting/nonreacting flows at …

In Liquid Rocket Engines, higher combustion efficiencies come at the cost of the propellants
exceeding their critical point conditions and entering the supercritical domain. The term fluid …

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 …

Supercritical nitrogen jet behavior is modeled using an incompressible but variable density
approach developed for variable density jets. Following mechanical and thermal breakup …

The injection of nitrogen under supercritical and transcritical conditions, where the injection
temperature is below nitrogen's critical point, but the pressure is above it, is considered in …
