The Shock Front Rise Time in Water.

Abstract

This paper reports on successful shock front optical reflectivity theory and experiment for water at 5.8 kbar (0.58 GPa), and complimentary shock induced electrical polarization experiment and theory for the pressure range 20 kbar to 100 kbar. The LCWSL - Universite de Poitiers program has experiments performed in France (funded by the Commission Nationale Recherche Scientique), while the ILIR program within the LCWSL funds the theoretical work. The consistent interpretation of the reflectivity and shock polarization results is (a) a shock front rise time of approximately 10-12 sec throughout the pressure range of 0 to 100 kbar, (b) a transition in the source of the dominant polarization voltage to the alignment of unbonded dipole moments at approximately 35 kbar, and (c) in the unbonded region the average contributing dipole is perfectly aligned in the direction of shock propagation.
