The degree of “imperfect mixing” induced by the macro mixing in the turbulent eddy scale is estimated by evaluating the probability density function versus the equivalence ratio.The procedure was proposed to evaluate the simplified discrete probability density function based on the measured average gas concentrations. The patterns of probability density function for three typical turbulent diffusion flames, with and without swirl, are presented to characterize the degree of imperfect mixing depending on the flame configurations and positions in the flame.
