Abstract

Abstract

The simulation of the explosion of expanded graphite bums agent requires the determination of the parameters in the JWL EOS of expanded graphite bums agent. The JWL EOS of expanded graphite bums agent are fitted through the differential evolution method taking condensed explosives isentropic line EOS as the target equation. The cylinder test results show that the maximum error between the theoretical value and experimental value is less than 3.3%, meeting the needs of the expanded graphite bums agent explosion simulation research.
