The Pareto-efficient combustion (PEC) framework is extended for predicting transient ignition in turbulent flames. The PEC formulation utilizes a drift term to assess the compliance of specific combustion submodels with the underlying flow-field repr

In several technical combustion systems for lean, premixed combustion, mixture stratification plays an important role, such as in stationary and aero gas turbines. The current paper focuses on a detailed characterization of a dual-swirl gas turbine m

Auto-ignition is a complex process which is extremely sensitive to boundary conditions such as local temperature, mixture or strain rate and occurs on very short time-scales. Therefore, measurement techniques with high spatio-temporal resolution have

Instantaneous 2D phosphor thermometry was performed on the windows and combustion chamber posts of an optically accessible dual-swirl gas turbine model combustor operated with CH4 at atmospheric pressure. Two phosphors were used in order to measure d
