Abstract
Interaction of homogeneous and heterogeneous detonation waves in mixtures of aluminum in oxygen and hydrogen in oxygen with a cloud of water droplets is studied by methods of mechanics of multiphase media. The main interaction mechanisms are determined: propagation of an attenuated detonation wave with a velocity smaller than the Chapman-Jouguet velocity and detonation failure. Critical conditions of detonation propagation in water sheets are determined. These critical conditions are compared with the results of modeling detonation suppression with the use of clouds of inert particles.
