Research covers the fields of combustion dynamics, acoustics, heat transfer and thermodynamics. In numerical methods a compressible non-adiabatic reaction progress variable combustion model was developed that can be applied on turbulent flows with LES or RaNS approach. The experimental research includes work on an atmospheric combustor in limit cycle oscillation and a pressurized combustor using laser diagnostics and multi microphone techniques. Specific applications studied are gas turbine engine power generation and propulsion. The main theme is pressurized and atmospheric combustion of sustainable fuels in gas turbine (aero) engines and furnaces and boilers. Fuels can be low calorific gases, NH3, H2 of jet fuel. Important phenomena studied are combustion stability, transient combustion behavior and emission of toxic species
