Numerical Simulation of Cryogenic Injection in Rocket Engine Combustion Chambers

Numerical Simulation of Cryogenic Injection in Rocket Engine Combustion Chambers

The numerical simulation of cryogenic combustion is crucial for a better understanding of the complex physics involved in reactive flows of rocket engines and to help to reduce the development cost of these engines. The focus of this study is set on the oxidizer injection and its dispersion through jet dense core destabilization and atomization or supercritical mixing. Specific models have been...

Scale Effects on Solid Rocket Combustion Instability Behaviour

The ability to understand and predict the expected internal behaviour of a given solid-propellant rocket motor under transient conditions is important. Research towards predicting and quantifying undesirable transient axial combustion instability symptoms necessitates a comprehensive numerical model for internal ballistic simulation under dynamic flow and combustion conditions. A numerical mode...

Engine-Level Simulation of Liquid Rocket Combustion Instabilities Transcritical Combustion Simulations in Single Injector Configurations

Detailed understanding of turbulent combustion in liquid rocket engines (LRE) requires an ability to predict the coupling between the transient features, acoustics, vortex/shear layer dynamics and the unsteady combustion heat release. Conventional and ad hoc models that mimic or match one set of conditions but fail in another test case cannot be used for reliable predictions. This paper present...

The Blacklight Rocket Engine

Executive Summary This report summarizes the final project results for the period of May 1, 2002 through November 30, 2002 for the NIAC CP 01-02 Phase I study, "The BlackLight Rocket Engine". The objective of the Phase I study was to assess the potential of low pressure, mixed gas hydrogen plasmas (i.e. the BlackLight Process) toward the development of high performance space propulsion systems.
