Numerical simulations of shock wave propagation in porous targets
Shock wave propagation in a nonuniform porous target consisting of granite grains is studied with the use of hydrocode modeling. The results show that a nonequilibrium type of wave propagation leads to formation of a high temperature vapor precursor in front of the shock. Deceleration of the shock i...

| Zusammenfassung: | Shock wave propagation in a nonuniform porous target consisting of granite grains is studied with the use of hydrocode modeling. The results show that a nonequilibrium type of wave propagation leads to formation of a high temperature vapor precursor in front of the shock. Deceleration of the shock in porous and compacted targets is found to depend on the initial wave velocity. Possible consequences of effects of porosity are briefly discussed. |
