NUMERICAL INVESTIGATION INTO THE PROPAGATION OF DETONATION WAVES IN INHOMOGENEOUS GAS SUSPENSIONS OF A MONOFUEL IN ABRUPTLY EXPANDING TUBES

The author has given results of a numerical investigation into the propagation of detonation waves in abruptly expanding tubes that are fully or partially fi lled with the gas suspension of a monofuel. The infl uence of the parameters of gas suspensions and a pipeline, and also transverse spatial nonuniformities of the concentration distribution of particles in the tubes have been studied. It has been established that the critical value of height of a transverse spatial nonuniformity decreases monotonically as the relative mass content of the suspension grows. Dependences of the critical diameter of particles on their relative mass content have been given.
