Shock-induced chemistry of phenylacetylene
Abstract
Gas gun-driven shock compression experiments of phenylacetylene using embedded electromagnetic gauging were used to obtain in situ particle velocity wave profiles at multiple Lagrangian positions at several shock input conditions. At shock conditions above 6 GPa, the input shock wave evolved over time and distance into a complex multiple wave structure due to shock-driven chemical reactions. The 3-wave structure was marked by a fast risetime 2nd wave, slower risetime 3rd wave, and unusual wave dynamics in the 1st wave. From the measured shock and particle velocities, the 1st wave, and intermediate and final product states associated with the chemical reactions were determined. A thermodynamically complete unreacted equation of state was calibrated to estimate the temperature rise along the shock locus. Use of this EOS with the measured 2nd and 3rd wave risetimes yielded highly statesensitive global reaction rates as a function of the shock locus.
