The computational technology was created for modeling the attenuation of a cellular detonation during the interaction of detonation waves with a rigid permeable barrier in flammable mixtures based on the ANSYS Fluent package. The reduced kinetic mechanism of acetylene combustion in air was verified using known experimental data. The interaction of detonation waves with a rigid permeable barrier was simulated. The dependencies of detonation attenuation modes on the geometric parameters of the obstacles were determined. Criteria for successful failure and preventing the re-initiation of detonation were identified. The contribution of the considered geometric parameters of the barrier to the attenuation of detonation is estimated. A comparison of the results obtained for acetylene-air and hydrogen-air mixtures was carried out.
Keywords: numerical modeling, detonation, detonation cell, chemical kinetics, detonation attenuation.
