Self-sustained combustion instabilities are one of the most plaguing challenges and
problems in lean-conditioned propulsion and land-based engine systems, such as rocket …

In engine combustion systems such as rockets, aero-engines and gas turbines, pressure
fluctuations are always present, even during normal operation. One of design prerequisites …

This contribution addresses the state-of-the-art in the field of aircraft noise prediction,
simulation and minimisation. The point of view taken in this context is that of comprehensive …

Open-loop control of self-excited flame pulsating oscillations and thermo-acoustic instability
is considered in this work. The performance of the control strategy is numerically evaluated …

In this work, a convection-driven Rijke–Zhao thermo-acoustic-piezo system is designed and

Porous foams may be classified into various sub-categories basing on their different
microstructures nature. Each type of foams is involved with different acoustic damping …

Unwanted combustion instability occurs in many propulsion systems, such as rocket motors,
and aero-engines. It is typically caused by a coupling between acoustic waves and unsteady …

In this work, the effects of the grazing flow and its geometric dimensions on the
aeroacoustics damping performance of a Helmholtz resonator are numerically evaluated …

As one of the most commonly used acoustic dampers, perforated liners are receiving wide
spread interest for reducing engine noise and stabilizing combustion systems. Generally …
