HIS paper describes the high frequency heat release response of laminar premixed flames
to perturbations in acoustic pressure, velocity and equivalence ratio. This work is motivated …

Low emissions combustion systems utilize a premixed combustion process that is prone to
combustion instability1-3. This phenomenon occurs when the unsteady combustion process …

Premixed flames respond to velocity perturbations with fluctuations in heat release rate
(“thermal response”), which in turn generate acoustic perturbations (“acoustic response”) …

Lean, prevaporized, premixed combustors are susceptible to combustion-acoustic
instabilities. A model was developed to predict eigenvalues of axial modes for …

In order to lower NOx emissions, lean premixed combustion was introduced by the gas
turbine industry. Combustion systems operating in this mode are, however, susceptible to …

This article describes recent progress on premixed flame dynamics interacting with acoustic
waves. Expressions are derived to determine the stability of combustors with respect to …

Lean premixed combustors, such as those used in industrial gas turbines to achieve low
emissions, are often susceptible to thermoacoustic combustion instabilities, which manifest …

HE objective of this study is to improve understanding of transverse combustion instabilities
in premixed combustors. It is a companion study to work presented in O'Connor et al.[1] …

Lean premixed combustors have been designed to lower NOx and other pollutant levels in
land based gas turbines. These combustors are often susceptible to thereto-acoustic …

HIS paper focuses on the direct response of premixed flames to transverse acoustic
oscillations in a cylindrical can combustor. The drive towards lower NOx emissions has …
