Estimate of the Post-Detonation Pressure and Temperature of TNT Charges in a Closed Chamber.
Abstract
When an explosive charge detonates in a closed chamber reverberating waves will for a short time determine the pressure-time history in the chamber. After several reflections, however, an equilibrium pressure will be reached, assuming no heat loss to the chamber during this short period of time. The objective of this report is to estimate the post-detonation pressure and temperature using some simplifying assumptions. The results could also be used as an approximation if the chamber has an outlet which is small compared to the chamber dimensions, or if the chamber breaks up and the inertia of the walls is large enough to prevent an appreciable movement during the time for the reverberating pressure waves.
