In this thesis, possible implementations of a rotating detonation engine (RDE) for energy generation are investigated and compared. In rotating detonation engines, unlike conventional systems, detonation of reactants is substituted to deflagration combustion, leading to an increase in the thermodynamic efficiency due to the higher temperature and pressure of the chemical reaction products. This thesis will concentrate on stationary RDE application for electricity generation, in contrast to most of the other studies on this topic, which primarily address RDE application for propulsion systems. Specifically, two rotating detonation combustor models will be presented, and different power plant configurations and thermodynamic cycles will be investigated and compared.
