Abstract

Abstract

In this paper, the method of obtaining parameters for JWL equation of state is investigated. The importance of JWL parameters considered detonation parameters is analyzed using simulation and theoretical calculation. Isentropic adiabatic index and detonation pressure of detonation product are calculated according to cylinder test. The methodology process for obtaining JWL parameters of ideal detonation product considered detonation parameters is established. The JWL parameters of two typical explosive are obtained with the application of this method according to published cylinder experimental result. The results of numerical simulation agree with the cylinder test so that the JWL parameters are reasonable and reliable.
