ATTENUATION OF DETONATION WAVES IN LAYERS OF HOMOGENEOUS AND INHOMOGENEOUS MONODISPERSE GAS SUSPENSION IN SHARPLY EXPANDING PIPES
Abstract
Mathematical simulation of the propagation mechanisms of combustion waves and heterogeneous detonation in sharply expanding pipes was performed using the equations of two-dimensional axisymmetric unsteady motion of a reacting mixture of a gas and monofuel particles.The interaction of a passing detonation wave in gas suspensions of a unitary fuel with an obstacle is studied.It is established that a decrease in the diameter of the particles of the unitary fuel leads to a decrease in the maximum pressure on the wall.It is shown that, under other identical conditions, the distribution of the concentration of particles of unitary fuel according to a linearly decreasing law leads to the greatest decrease in the maximum pressure on the barrier than according to a linearly increasing and homogeneous one.
