Research Topic

Gas turbine engines are the most efficient engines for power generation at a scale of 20-400 MW, combining a very compact design with low maintenance and high reliability. Nevertheless their robustness could decrease when some parts of engine are exposed to an anomalous oscillating pressure load. This load is generated by thermo acoustic instabilities, which are violent oscillations caused by feedback between combustion and pressure waves.

The LIMOUSINE project, which is inside of FRAMEWORK 7 brings a multi-disciplinary approach to study these phenomena. Academic, Research Institutes and Industrial partners work together in different aspects of the problem. The communication between partners becomes of the utmost importance.

My task in the project is experimentally investigate how thermo acoustic instabilities occur in high pressure combustor. The Experimental setup is designed within the framework of the DESIRE project is able to work with a maximal thermal power equal to 500 kW at 5 bar absolute pressure. The burner is of the radial swirler type (with a swirl number of 0.7). Natural gas is used as a fuel in technically premixed mode operation.
