摘要：

The interaction of a detonation wave in a hydrogen-air mixture with a series of clouds of inert particles with diameters of 1, 10, and 100 mm is calculated. The concentration and geometric limits of detonation are determined. It was found that an increase in the particle diameter leads to an increase in the concentration limit and to decrease in the geometric limit of detonation. It has been found that an increase in the number of clouds in a series of clouds makes it possible to increase the length of the gaps between them for the successful failure of detonation. In addition, the longer the clouds of inert particles, the greater the maximum distance between them and the smaller their number is necessary to quench the detonation.
