THEORETICAL VERSUS EXPERIMENTAL RESULTS FOR AIR BLAST FROM ONE-POUND SPHERICAL TNT AND PENTOLITE CHARGES AT SEA LEVEL CONDITIONS

Abstract

Numerical computations, using a one-dimensional hydrodynamic code on an IBM 7090, were made for the detonation of 1-lb spheres of pentolite and TNT at sea level. Positive durations, overpressure at the main shock, and space- time paths of the main shock, second shock, and contact surface are compared with experimental data. It is found that the calculated peak pressures at the main shock are 10 per cent too low, the experimental second shock path lies about 40 per cent above the calculated one, and the experimental contact surface path is about a factor of two greater in radius than the calculated one. Possible explanations for these deviations are discussed.
