Abstract
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.
