High-Pressure LPRE Combustion Dynamics: Low-Cost Computation and Stochastic Analysis
Abstract
The objective of this proposed research is to develop 3D multi-fidelity model to capture detailed physics in the liquid rocket combustion instabilities, by incorporating detailed kinetics, nonlinearities, and unsteady vortex dynamics, and the real gas effects. In addition, reduced order models will be developed by training multi-fidelity models with deep learning neural networks, such that proper basis functions will be developed. Both multi fidelity model and the reduced order models will be subject to the stochastic analysis to predict triggering instabilities.
