Prediction of Detonation Velocities of Non-metal Nitrated Explosives by Simple Method

Abstract

A simple method is introduced for determining detonation velocities of non-metal nitrated explosives, which have significantly non-ideal behavior. The number of moles of different atoms in 100 g of pure or mixture and condensed phase heat of formation of explosives are sufficient for reliable simply prediction of detonation velocity as compared to complicated computer codes. Detonation velocities for non-metal nitrated explosives with the general formula C_aH_bN_cO_d are predicted by the equation:

D (km/s) = (–3.748/r₀) – 13.438a + 13.033b – 28.632c + 24.704d + 0.7265 DH_f

where r₀ is loading density and is DH_f is crystalline heat of formation. This procedure for non-metal nitrated explosives, which have non-ideal behaviour, shows good agreement with experimental values.
