Detonation waves in polydisperse gas suspensions of monofuel in tubes with an abrupt expansion

Abstract

The distinctive features of detonation wave propagation in polydisperse (double-fraction) gas suspensions of a monofuel in tubes with an abrupt expansion are numerically investigated. Numerical calculations are performed for different sizes and relative mass contents of the particles of both fractions. A comparative analysis of the effect of mono- and polydisperse monofuel particles on the detonation wave mitigation is made. The dependences of the critical tube-diameter ratio of a sectional pipeline on the relative mass content and polydispersity of monofuel particles with different sizes are presented.
