Eigenvalue detonation of nitromethane and its failure
We present a model and implement a procedure that obtains the detonation velocity-diameter effect of liquid explosives by solving the quasi-one-dimensional conservation equations with source terms for mass, momentum and energy transfer. This analysis has been applied to the case of liquid nitromethane as a test bed. The results predict a detonation velocity deficit of less than 2% at the failure diameter, which is consistent with previous experimental results. With an Arrhenius reaction rate law, failure diameters of 15–18 mm are obtained for activation energies in the range of 30–40 kcal/mole. The detailed structure of the detonation zone is also obtained in the determination of the eigenvalue detonation solution.
