Abstract:

Previous studies of the shock-flame interaction processes are critically reviewed. Experimental observations reported in the literature are analyzed by means of the Vector Polar Method which provides information on the stationary states produced by the interactions rather than on the processes that occur in the course of their progress. Results of our experimental study performed with the use of hydrogen-oxygen mixtures at low initial pressures are then presented and interpreted by the use of the same method of analysis. The study leads to the following conclusions 1 a satisfactory explanation of the interaction effects can be obtained on the basis of gasdynamic analysis, provided that proper allowance is made for the finite change in the relative flame propagation speed 2 the most important result of the interaction process is the change in the flamefront structure and 3 the amplification of the propagation velocity of the flame is associated with the breakup of its front into a space distributed reaction zone.
