Numerical and analytical study of combustion instabilities in industrial gas turbine

This study explores numerical and analytical methods to investigate combustion instabilities in an industrial gas turbine. The three-step approach includes an analytical model, application to an industrial test rig, and conclusions. Various parameters and assumptions are considered, and simulations are compared to experimental data.
