Abstract:

Supposing that the homogeneous turbulent mixing of a passive, scalar contaminant is statistically known, it would be desirable to learn what differences will result from incorporating chemical reactions. The long range goal is turbulent combustion, in which the large random heat release probably feeds back into the fluid dynamics. The paper touches upon two classes of problems 1 estimates of decay rates of average concentrations and isotropic concentration fluctuations, 2 estimates of the forms of Fourier power spectra for locally isotropic, statistically stationary fields. Three idealized, irreversible, passive, chemical reaction types are mentioned a first-order, isothermal, b second-order, isothermal, c first order, slightly exothermic. The spectral estimates employ a generalization of Onsagers turbulence cascade theory. Author
