Direct numerical simulation and modeling study of turbulent combustion in gas turbine engines

The goals of this research are to achieve: (a) a predictive and cost-effective CFD modeling tool that can be used by industry in the analysis and design of turbulent combustion processes in gas turbine engines, based on the CCM/PDF transport model, (b) a deep understanding of the physical and chemical processes in the involved turbulent combustion processes, including the onset of flame instability and its impact on flame flashback and stabilization in gas turbine combustors, and (c) a well-documented DNS database for the laminar and turbulent burning velocities of various flames, which takes into account the effect of flame instability on the propagation of laminar flames and turbulent flames under high-pressure and a range of turbulence conditions. These database, understanding and prediction tool are crucially important for the industry to design and analyze future generation gas turbines firing with different fuels, with reduced design period and low development cost.
