The document summarizes simulation results of explosions in a 1.2 m3 vessel filled with varying amounts (0%, 50%, 100%) of AXS aluminum mesh. The simulations showed that adding AXS reduced explosion pressure and temperature in a dose-dependent manner. Comparison of simulation results to experimental data found excellent agreement, validating the model. It was concluded that AXS is effective at mitigating explosion hazards from liquefied petroleum gas and is ready for use.
