Project description

Spray flame dynamics in gas turbine combustors

Gas turbines find a wide application for power generation and aviation. Increasingly stringent emissions regulations have resulted in new combustion chamber designs capable of operating with low amount of fuel reducing the emission of nitrogen oxides. These new designs and lean operative conditions promote thermoacoustic instabilities, i.e. dangerous oscillations resulting from a resonant coupling between combustion and a system's acoustic modes. These instabilities can lead to mechanical failure of system components and must be avoided. The EU-funded CLEANERFLAMES project will investigate these combustion unsteady phenomena in the case of liquid fuel injection as a spray through a combination of experimental and numerical approaches. Enhanced understanding will support the system designs to enhance engine stability and performance.
