Robust-Mode Analysis, Reduced-Order Modeling, and Intelligent Control Strategies for Reacting and Non-Reacting Flows

This Phase-II STTR research effort is designed to forward the engineering investigation of the dynamics and control of turbulent combustion in high-pressure combustion systems by developing a set of game-changing nonlinear analysis tools that can significantly improve the post-processing speed and intelligent data mining of large numerical or experimental data sets. Moreover, a system based on nonlinear dynamical phase-space analysis (such as Chaos Theory) will be explored for reduced order modeling (ROM), devising control strategies, and providing quantitative information for system identification and comparison. The preliminary results of some of these analysis approaches were demonstrated during the Phase-I research effort on experimental data provided by Edwards AFB and numerical data related to the CVRC combustor. The final deliverable of this research effort will be user-friendly software incorporating various mathematical tools for analyzing experimental and numerical data. It is expected to have a range of applications, including establishing quantitative differences between experimental flows and validating models of various experimental systems. The software will contain a user-friendly interface that can be used to pre-process the data, construct reduced order models, test and refine various control strategies, and compute the dynamical invariants for the dynamics. The approaches proposed in this research effort will
