Application of the ESCIMO theory to turbulent diffusion flames
Abstract
In order to assess the validity of the ESCIMO theory for turbulent diffusion flames, predictions and measurements of the diffusion limited chemical reaction in a turbulent mixing layer; the hydrogen-air diffusion flame in coflowing air; and the natural gas-air free jet diffusion flame are compared. The mean velocity and the turbulent kinetic energy; the population distribution function of various folds; the variation of mean temperature and species concentration across the mixing layer or jet; the rms fluctuation of temperature and species concentration; and the probability density function of temperature and species concentration are obtained. Agreement between prediction and measurement are good, but inclusion of turbulence intermittency in the theory is advocated.
