Detonations graphical representation

Figure 13, which is a graphical representation of the ZND theory, shows the variation of the important physical parameters as a function of spatial distribution. Plane 1 is the shock front, plane 1 is the plane immediately after the shock, and plane 2 is the Chapman-Jouguet plane. In the previous section, the conditions for plane 2 were calculated and u was obtained. From u and the shock relationships or tables, it is possible to determine the conditions at plane 1. Typical results are shown in Table 5 for various hydrogen and propane detonation conditions. Note from this table that (/02/yOi) = 1.8. Therefore, for many situations the approximation that is 1.8 times the sound speed, 02, can be used.

Fig. 24 Graphical representation of the E-P-S relation (Eq. 10) between the squares of the experimental detonation rates of explosive mixtures and the slopes, a-R" > of Kissingers relationship (Eq. 7)—taken from [153], Black points correspond to dynamites with a nitric ester content of over 30 wt %. Oxidizing systems of all of these explosives are based on ammonium nitrate (AN) and its mixtures with sodium nitrate (SN), potassium nitrate (PN), calcium nitrate (CN), aluminium nitrate (AlN), lithium nitrate (LiN), and sodium chloride-sodium nitrate (NaCl/SN), nickel(II) nitrate (NiN), copper(II) nitrate (CuN) and cobalt(II) nitrate (CoN)...
