Abstract

A complex numerical simulation where blast waves interacted with a liquid, burnable simulant inside a chamber was conducted. The liquid simulant was dispersed by a small high explosive (HE) charge and then impacted by the blast wave produced by a significantly larger HE charge. The physics of the problem required numerical tools that allowed for (1) coupling of compressible and near-incompressible (+VOF) solvers, (2) a dropletization model by liquid bulk dispersion, (3) droplet breakup and vaporization, (4) a chemical package for combustion, and (5) a particle update technique. The resulting numerical code successfully simulated the scenario, and the predicted pressure agreed excellently with the measured data.
