THE LOCATION OF THE CHAPMAN-JOUGUET PLANE FOR A GRANULAR EXPLOSIVE BY THE EFFECT OF AREA INCREASE ON DETONATION VELOCITY

Abstract

The detonation velocity for a granular mixture of potassium perchlorate and aluminum confined in a Lucite tube and an ideal detonation velocity calculated by the RUBY Computer Program were used together with the observed reaction zone profile to estimate the position of the Chapman-Jouguet plane with respect to the plane at which reaction commences. This was done by extending Jones equation for effect of radial expansion on the detonation velocity to include the effect of covolume a function of volume. It was found that the CJ plane is about 0.9 cm. behind the plane at which reaction commences.
