Numerical study of detonation waves in a monofuel-gas mixture in sharply expanding pipes

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 influence of the main determi...

Summary: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 influence of the main determining parameters of the gas-particle mixture and the pipeline on the propagation of nonstationary detonation waves was studied. Dependences of the critical ratio of the pipe diameters of the composite pipeline on the relative mass content of monofuel particles of different sizes are given.
