Abstract

A study was conducted to demonstrate the use of the picosecond time-resolved laser-induced fluorescence (PITLIF) technique to measure hydroxyl (OH) time series and a dynamic pressure sensor to obtain pressure time series in a Schmidt tube combustor. The stationary portions of simultaneous hydroxyl and pressure time series were analyzed by employing singular spectrum analysis (SSA). The noise-reduction capabilities of SSA were discussed from the point of view of instability mitigation in propulsion systems. A fast Fourier transform (FFT) was applied to the original and reconstructed time series to demonstrate the noise-reduction capability of SSA. Successful reconstruction and noise reduction were also demonstrated for extremely noisy and nonstationary time series.
