The detonation velocity of pressed TNT has been determined as a function of charge diameter at each of a series of loading densities ρ. Current theories of the diameter effect are discussed and used to compute infinite diameter detonation velocities (D∞) and detonation reaction‐zone lengths from the experimental data. The results for the velocity‐density dependence may be summarized as follows: D∞ = 1872.7 + 3187.2 ρ, (0.9 ≤ ρ ≤ 0.5342 g/cc); D∞ = 6762.5 + 3187.2 (ρ − 1.5342) − 25 102 (ρ − 1.5342)2 + 115 056 (ρ − 1.5342)3, (1.5342 ≤ ρ ≤ 1.636 g/cc). The reaction‐zone lengths computed from the data are a decreasing function of the charge density and are in good agreement with predictions based on the grain‐burning model of the reaction zone. |
