Abstract

This paper deals with blast waves generated by a bursting spherical vessel filled with a pressurized gas. A large number of numerical simulations are performed. From the results of the simulations, a simple model comparable to the TNT-equivalent model is derived. The new blast wave model consists of a single relationship between the scaled peak overpressure and the scaled distance. Moreover, a closed-form expression for the explosion efficiency as function of the initial velocity only is provided.
