Detonation Failure

An analytical steady-state theory of the detonation ‘diameter effect’ is presented. This theory, which includes the off-axis flow, is a generalization of the Wood-Kirkwood analysis. When the state dependence of the reaction rate is stronger than that of the product of the sound speed squared and the flow divergence, detonation failure can occur. The leading term in the extrapolation of the detonation velocity to infinite charge size is quadratic in the inverse charge size and not linear as popularly believed. When calibrated to the detonation velocity vs. charge-size data, the theory reproduces the limited amount of experimental shock loci to a high degree of accuracy.

Detonation Failure

A computational technology for direct modeling of the detonation waves interaction with a set of particles at the micro level has been developed. A simulation of the detonation waves passage through a system of particles with their different relative positions was carried out. Stoichiometric hydrogen air mixture is considered. The combustion process is described using a reduced kinetic mechanism. Estimates of the ratios between times of the velocity and thermal relaxation are obtained. Detailed shock-wave patterns of gas flow in the particles vicinity are obtained. The possibility of detonation failure at particles volume fractions of close to the concentrations obtained in modeling at the macro level has been revealed.
