Theoretical calculations of the phenomenology of an atmospheric high- explosive detonation are presented. The charge was a 100-ton sphere radius, 240.5cm of TNT loading density, 1.56 gmscc whose center was at an altitude of 646.405 meters. The ground, upon which the spherical charge rested, was 644 meters above sea level. The numerical calculations taken out to 6 seconds were performed on the CDC 6600 digital computer using SHELL2, a two-material version of the SHELL-OIL code, two-dimensional pure Eulerian hydrodynamic code. Air and the detonation products of TNT were the two materials considered in the calculation. The analytic, self-similar solution for the detonation wave in TNT provided the initial conditions. Included are pressure and density contours, velocity vector plots, and wave forms for 19 test stations. This calculation is a representation of the air blast of Event 6 of the DISTANT PLAIN test series to be fired in Canada, July 1967.
