Influence of Chemical Kinetics on Electrical Turbulence.

Abstract

Theoretical models that predict the influence of chemical kinetics on the spectral distribution and spatial correlations of positive ion concentration fluctuations are developed. Calculations, based on these models, are shown to be consistent with data taken in turbulent clean and potassium-seeded propane/air flames at one atmosphere--in the region where electron-positive ion recombination is the dominant kinetic mechanism. The results show that the ratio of chemical time scale (time for ion concentrations to decrease to 1/e of their initial value) to turbulent time scale (eddy break-up time) is the key parameter in determining when electron-ion recombination rates influence electrical turbulence.
