Effect of Charge Radius on Detonation Velocity

Abstract

The derivation of the detonation velocity of an ideal wave in an imperfect gas obeying the equation of state of the form pv = nRTe(K/v) is given. Assuming the curved-front theory, the effect of radial expansion on the velocity of propagation of a non-ideal detonation wave is treated using the above equation of state. The significant approximations involved are discussed and the final equations are given in a form easily applied to experimental data. The results of this study suggest that longer reaction zone lengths than those previously obtained using a constant co-volume may be appropriate.
