Modelling of unsteady combustion in low emission systems


All low emissions combustion systems suffer from acoustic instability, and this is often the major issue preventing wide application of the technology. This proposal addresses the issue of how this important combustion phenomenon should be represented in design tools. Experiments are proposed which will identify the mechanisms by which acoustic disturbances cause variations in the aerodynamics or fuel spray behavior. These in turn give rise to heat release variations, thus establishing the feedback mechanisms that cause damaging pressure waves. These results will form the basis of a design methodology to prevent such oscillations occurring.
