The verification basis of the ESPROSE.m code Original Research Article

An overall verification approach for the ESPROSE.m code is presented and implemented. The approach consists of a stepwise testing procedure from wave dynamics aspects to explosion coupling at the local level, and culminates with the consideration of propagating explosive events. Each step in turn consists of an array of analytical and experimental tests. The results indicate that, given the premixture composition, the prediction of energetics of large scale explosions in multidimensional geometries is within reach. The main need identified is for constitutive laws for microinteractions with reactor materials; however, reasonably conservative assessments are presently possible.
