Influence of Fuel Inhomogeneity and Stratification Length Scales on Detonation Wave Propagation in a Rotating Detonation Combustor (RDC)
… present study is to investigate the impact of unmixedness and stratification length scales on the performance of an RDC using a 2-D numerical approach. Unmixedness, which is defined as the standard deviation of equivalence ratio normalized by the mean global equivalence ratio, is a measure of …

Fuel/air Mixing and Nitrogen Oxide Formation in a Lean Premixed Gas Turbine Combustor
… obtained by including the effects of reactant unmixedness based on the fuel/air distribution measurements recorded during the non-reacting mixing studies.

Numerical Simulations of Multi-Confined Jets in Crossflow at Supercritical Pressure
… using image processing and method of Spatial Unmixedness. This technique provides a measure of unmixedness based on the variance of the concentration distribution which is defined as “spatial unmixedness, Us “. Having an Us = 0 corresponds to a perfectly mixed system, and Us= 1 indicates a …

Experimental Investigation of a Lean, Premixed Gas Turbine Combustor Using Advanced Laser Diagnostics
… but were generally low, indicating low levels of unmixedness.

Numerical modeling and simulation of compressible reacting turbulent shear layers
… are also presented. The importance of modeling unmixedness and its effect on chemical reaction and heat release are clearly illustrated. The above models are developed and validated in a new parabolized Navier-Stokes (PNS) code.

Concentration And Velocity Fields Throughout The Flow Field Of Swirling Flows In Gas Turbine Mixers
Air velocity and fuel concentration data have been collected throughout the flow fields of two gas turbine mixers in an effort to better understand the mixing of fuel and air in gas turbine mixers. The two gas turbine mixers consisted of an annular flow profile and incorporated swirl vanes to …
