Capillary hydrodynamic phenomena in gas-free combustion

The capillary effects of gradient filtration and melt microflows in combustion waves of heterogeneous systems are analyzed on the basis of experimental data obtained by video recording, local dynamic pyrometry, and investigation of hardening structures. Relations between the parameters of convective phenomena and combustion dynamics and the mechanism of activation of the heterogeneous combustion interaction by melts are established for Ti–B–Cu, FeO–Al–Al$_2$O$_3$, Ni–Al, and Ti–Ni powder mixtures and model bimetallic compositions.
