In this work, we develop a 2D numerical model of a Y-shaped bifurcating combustor with a
Helmholtz resonator attached. Propane (C 3 H 8) is fueled and burnt with air by applying …

The blending characteristics of ammonia with conventional fuels have recently received
much attention from researchers. This paper investigated the effect of acoustic excitation on …

Thermoacoustic instability (TAI) poses a significant challenge to the development of solid
rocket motor (SRM) and detecting early warning signals (EWS) for TAI is crucial. Deep …

A comprehensive study on the influence of the unsteady non-reactive flow characteristics of
turbulent flow in a three-stage swirl combustion chamber using power spectral density …

Nacelle acoustic liners inevitably generate greater aerodynamic drag than smooth walls. It is
necessary to study the factors influencing acoustic liner drag to reduce engine fuel …

This paper presents a tunable combustor outlet geometry, which enables control of
thermoacoustic instabilities. It is based on a water-cooled conical piston inserted in the outlet …

This paper presents a newly commissioned grazing flow tube facility at the Hong Kong
University of Science and Technology to study the characteristics of acoustic treatments …

Large eddy simulations and power spectral density methods are used to investigate the
unsteady non-reaction flow characteristics, as an important phenomenon in the combustor …

Ammonia is one of the promising carbon-free alternative fuels for low-carbon power
generation. This study investigated the self-excited thermoacoustic instability of premixed …

Self-excited thermoacoustic oscillations are undesirable in most combustion systems due to
their negative influence on combustion efficiency and structural vibration. Nonlinear …
