Abstract: This paper deals with passive stabilization of thermoacoustic dynamics in a Rijke tube using a Helmholtz resonator. Thermoacoustic instabilities result from the dynamic coupling between the heat release and pressure in a ...

Abstract: This paper offers two interlinked contributions in the field of vibration absorption. The first involves an active tuning of an absorber for spectral and spatial variations. The second contribution is a set of generalized ...

Abstract: The delayed resonator (DR) is an active vibration absorber, which yields ideal vibration suppression at its resonance frequency. In this study, we further complement the DR design in a distinctive mechanical path by ...

Abstract: The stability boundaries of LTI timedelayed systems with respect to the delays are studied in two different domains: (i) delay space (DS) and (ii) spectral delay space (SDS), which contains pointwise frequency information ...
