Rocket Engine Large-eddy Simulations with Advanced Modeling of Multi-injectors and Flamelets
Abstract
The research addresses the complex combustion dynamics and complex configuration found in practical liquid-propellant rocket engines (LPRE). The key goal is to increase substantially our understanding of the destructive combustion instability and thereby support the longer-term aim of the Air Force to improve rocket engine performance and reliability. The proposed research is aimed to understand and control better the complex combustion dynamics found in practical liquid-propellant rocket engines (LPRE). The challenge involves the need to understand fully the unsteady, multi-scale, multi-dimensional behavior which results from a combination of turbulence, larger-scale chaotic behavior, nonlinear acoustics, and the interactions across these physical occurrences. The large-amplitude, destructive oscillations must be avoided or suppressed.
