Abstract
The capability to predict the consequences of explosion through computer simulations is of great practical importance. The physical processes involved in a detonation phenomenon, though, are extremely complex. Therefore, the common practice is to resort to empirical or semiempirical equations of state (EOSs) describing the detonation properties of explosives. Becker–Kistiakowski–Wilson (BKW) and Jones–Wilkins–Lee (JWL) are among the most widely used EOS. The purpose of this work is to conduct a comparative study between them. A special emphasis was given to the description of the contaminants dispersion caused by the explosion (in addition to the usual interest in describing blast waves). In particular, we study the implications of these differences within the framework of our current computational methodology using the open source CFD toolbox—OpenFOAM [1].
