This paper presents results from numerical simulations of a non-premixed hydrogen-air
rotating detonation combustor with radial injection. The fuel and air mass flow rate are varied …

Large eddy simulations (LES) of self-excited spray combustion instability in an aero-engine
combustor are performed to investigate the mechanisms of combustion instability. Three …

Liquid rocket, Diesel or aircraft engines may operate in the transcritical regime. In such
thermodynamic conditions, the classical phase change that occurs at subcritical pressure …

Because of the extreme complexity of physical phenomena at high pressure, only limited
data are available for solver validation at device-relevant conditions such as liquid rocket …

Rotating detonation rocket engines (RDREs) exhibit various unsteady phenomena,
including modal transitions, that significantly affect their operation, performance and stability …

At supercritical conditions, thermodynamics may become strongly nonlinear which is
reflected by large thermodynamic Jacobian values. This means that small variations in …

Abstract The Large-Eddy Simulation of a reduced-scale rocket engine operated by DLR has
been conducted. This configuration features 42 coaxial injectors fed with liquid oxygen and …

This article describes a numerical investigation that explores the dynamics of multiple
cryogenic jet flames interacting with high frequency transverse acoustic modes. This …

Supercritical combustion has attracted significant interest due to its applications in high-
pressure combustion devices. Validation of supercritical combustion modeling, however …

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 …
