The proposed research aims at developing a novel theoretical and numerical framework to predict and control combustion instabilities in a new type of combustion chambers for the next generation of heavy-duty gas turbines. This technology step change is based on constant pressure sequential combustion architectures and provides higher fuel and operational flexibility and higher efficiency and power compared to modern single stage combustion chambers. In particular, it will be fuel-flexible and capable of burning conventional gaseous and liquid fuels as well as bio- and syn(thetic)- gas on demand. This research will provide essential tools for sequential combustor development and optimisation. Active control of combustion instabilities in sequential combustion systems using non-thermal plasma will also be investigated at high pressure, which is the first step toward a practical usage of this control technology and which could constitute a further improvement of the constant pressure sequential combustion systems.
