Review of acoustic field effects on flame dynamics and combustion applications

International Journal of Coal Science & Technology
Acoustic-flame coupling technology is an interdisciplinary frontier field investigating the complex interactions between sound waves and combustion. Generally, the acoustic field can be divided into two modes based on its relative position to the flame ...

Modeling and control of thermoacoustic instabilities

, 2003
This work deals with modeling and control of thermoacoustic combustion instabilities in lean premixed combustion systems. Because of the complex interactions present in thermoacoustic systems, a network modeling approach is used. The model of each network element or subsystem is obtained analytically, numerically, or by making use of experimental ...

UV and Visible Radiation Characteristics of Thermoacoustic Instabilities in an Ammonia–Methane Premixed Swirl-Stabilized Combustor

Energies
Ammonia (NH3) is a promising carbon-free energy carrier for low-carbon power generation. However, in turbulent ammonia–methane (NH3-CH4) premixed swirling flames, operating at lean conditions to limit NOX, emissions can trigger strong thermoacoustic ...

Predicted Thermoacoustic Flame Response at Megawatt Scale in a Near-Stoichiometric Atmospheric Industrial Furnace

Energies
While gas-turbine combustors have received much research attention, the forced response of large atmospheric industrial flames is much less studied. To improve the understanding of thermoacoustic instabilities in industrial combustion systems, the forced
