Effect of gaseous oxidizer composition on the detonability of isooctane-air sprays

Numerical simulations have been performed with the EFAE code, with taking in consideration the chemical composition of the oxidizing phase and the effects of the two-phase mixture richness. Results of 2D and 3D numerical simulations, as a function of the equivalence ratio and the dilution, display propagation regimes and detonation cell sizes in reasonable agreement with the experimental results.
