Combustion oscillations in a ducted burner
Unsteady combustion, confined within a duct, is a poorly understood and incompletely documented phenomenon. This is particularly true of the violent, low frequency combustion oscillation encountered in gas turbine reheat systems, commonly referred to as reheat buzz. This thesis describes an …

Feedback control of oscillations in combustion and cavity flows
This thesis considers the control of combustion oscillations, motivated by the susceptibility of lean premixed combustion to such oscillations, and the long and expensive development and commissioning times that this is giving rise to. The controller used is both closed-loop, employing an actuator …

Active Stabilization of Thermoacoustic Oscillation
Combustion processes serve as important sources of energy for both power generation and for transport, ranging from large scale power stations to micro turbines and aeroplane engines. Lean premixed combustion offers a potential to reduce the emission levels, but suffers from instability problems …
