Mixture Fraction Consider a nonpremixed (diffusion) flame with a single fuel stream and a single oxidizer stream. We can define the ixture fraction characterize the extent of mixing in the mixture fraction f to characterize the extent of mixing in the flowfield irrespective of the extent of reaction at that point: mass of material originating from fuel stream ass of mixture f mass of mixture School of Mechanical Engineering, Purdue University 3/7
