Vf. Proskudin, Recording local fluctuations of physicochemical parameters in a combustionwave in condensed systems, COMB EXPL R, 35(6), 1999, pp. 666-669
A method for recording fluctuations of physicochemical parameters in a comb
ustion wave in condensed systems is proposed that makes it possible to esti
mate the frequency of these fluctuations experimentally. Experiments with a
Zr + WO3 pyrotechnic mixture using this method show that in the combustion
wave there are fluctuation modes with frequencies approximate to 200 and a
pproximate to 20 Hz corresponding to characteristic dimensions of heterogen
eities of the system of order 0.1 and 1 mm, respectively.
