Keywords: gas turbine combustion, large eddy simulation, combustion instabilities

As gas turbines are often operate close to the lean stability limit, combustion oscillations are key design parameters. Here we use compressible reacting Large Eddy Simulations to develop detailed understanding of the dynamics of a multi-burner annular gas turbine combustor including the effects of fuel and swirler characteristics.
