[en] Aerothermoballistic behavior of pyrophoric metal shrapnel ejected at supersonic speeds has been numerically simulated. The theoretical model predicts aerodynamic and chemical heat-transfer rates and particle thermal response, including time and position of melt initiation. Because of the high Weber number environment, the melting particle undergoes liquid layer stripping. The model, incorporated in the PLUTO computer code, predicts the liquid mass loss rate, characteristic liquid droplet diameter, temperature rise across the liquid film, and the coupled particle trajectory. The aeroheating, thermal, and ballistic sections of the PLUTO code have been validated by comparison with independent calculations and qualitative experimental data concerning the melting and ablation of gold microspheres. The model still needs to be field tested against reactive metal particles in high Weber number flows
