Numerical modeling of suppression of detonation waves in hydrogen-air mixture by system of inert particles clouds

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.

Automated summary

This study calculated the interaction between a detonation wave in a hydrogen-air mixture and a series of clouds of inert particles with diameters of 1, 10, and 100 mm, and determined the concentration and geometric limits of detonation. It was found that increasing the particle diameter increases the concentration limit and decreases the geometric limit. Moreover, increasing the number of clouds in a series allows for longer gaps between them, facilitating the successful suppression of detonation.
