Reducing the footprint of greenhouse gases and nitrogen oxides (NOx) emissions from
combustion systems means that they have been operating under lean or ultra-lean fuel–air …

Many aero-engine and gas turbine combustion systems are in choked configuration. These
combustors are more prone to thermoacoustic instability. Thus there is a need to …

Thermoacoustic instability occurs in many practical combustion systems. These systems are
non-normal and associated with transient growth of acoustic disturbances. If the transient …

The present study numerically simulates self-excited instabilities of hydrogen-blended
natural gas flames in a lean premixed gas turbine combustor with variable chamber length …

When aiming to cut down on the emission of nitric oxides by gas turbine engines, it is
advantageous to have them operate at low combustion temperatures. This is achieved by …

The time-domain impedance boundary condition (TDIBC) is used within a large-eddy
simulation (LES) framework to investigate self-sustained longitudinal combustion instability …

This paper proposes a new approach for one-dimensional thermoacoustic combustor
models. Our new model is a transfer function estimated from the frequency response of the …

This paper presents a method for predicting the stability boundaries of a model combustion
chamber using a data-driven approach based on the n-τ model. The n-τ model is derived …
