Supercritical CO2 (sCO2) power cycles are gaining the attention of industry and academia due to their attractive features such as efficiency, eco-friendliness, compactness, and cost. However, the development of a combustor for direct-fired sCO2 cycles is challenging due to very high operating pressures. Therefore, accurate CFD simulations play a major role in the initial design and development of this combustor. In the current study, the applicability of various flamelet assumptions for supercritical CO2 combustion is discussed and variation of important non-premixed combustion characteristics with dilution and pressure are discussed. Here, chemistry is tabulated using the opposed jet diffusion flame flamelet approach with real-gas corrections.
