A Three-Dimensional Calculation of the Venting Process for an On-Axis Explosion in the MX Trench

Abstract

Using the TRIDORF code, we performed a three-dimensional calculation to study the venting of energy through the roof of the proposed MX missile emplacement trench for an on-axis detonation of 1 Mt. A two-dimensional calculation to 27 microsecond by Science Applications, Incorporated, gave us the initial conditions; our calculation extended to 238 microsecond, through the period in which venting and asymmetrical tunnel expansion are the major energy- transfer processes in the trench. These two calculations provide the best available starting conditions for later 1-1/2 and 2-dimensional calculations of the downstream flow.
