“…Further processing of experimental results in [31,32] made it possible to approximate the shock adiabatic curve of water by three linear segments for which the correlations and limits of validity were found by successive fitting of values of D(U) from the total array of experimental data. The dependences obtained in [32] are given in Fig.…”

The results of measurements of the shear viscosity of shock-loaded water, obtained by the method of decay of perturbations on a corrugated shock front suggested by Sakharov et al. [1], are treated in the light of new data on the phase diagram of water. The experimental data on viscosity in the pressure range from 4 to 25 GPa are compared to the results of measurements by other methods. The high values of viscosity at high pressures are attributed to the formation a water-ice VII mixture under shock compression of water.

Substitution of energy from EOS equations to the conservation equations results in a cubic polynomial equation for reflected pressure, roots of which yield pressure reflection coefficient ðC R Þ or the ratio of the reflected shock pressure to the incident shock pressure.…”

Proc. 1479, 2352 (2012); 10.1063/1.4756666Nonlinear compressibility effects in fluid-structure interaction and their implications on the air-blast loading of structures A novel theory has been developed for underwater explosion induced shock wave loading considering nonlinear compressible medium both front and back of the free standing rigid plate. Both analytical formulation and numerical simulations have been performed in this manuscript for different type of shock loading profiles, different plate masses as well as different backing conditions of the plate. The results obtained have been asymptotically validated against existing theories in acoustic range. Impulse transmission, maximum momentum transfer, and cavitation inception have been determined for different cases and have been shown to be dependent on the fluid structure interaction parameter as well as the backing condition of the plate. Impulse design transmission curves have also been developed for plates of intermediate mass for different shock intensities and profiles thereby removing the need to perform numerical simulations. The major conclusions of the paper are that nonlinear compressibility and varying pressure back of the plate further enhance the beneficial effects of fluid-structure-interaction in reducing impulse transmitted to the structure. These results can be advantageously exploited for design and optimization of light weight underwater structures with increased blast resistance. V C 2012 American Institute of Physics.

“…The simultaneous high-pressure and high-temperature phase of a material can be typically achieved through dynamic compression experiments. It has been reported in experimental studies that dynamic compression of bulk liquid water at certain intensities results in its phase transformation to a 'likely ice VII crystal structure' [1][2][3][4][5][6]. Most of these experimental studies perform 'ramp compression' or quasi-isentropic compression; eventually, in all of these studies, the final state of the dynamically compressed sample is at a high-temperature and high-pressure regime corresponding to the ice VII phase.…”

Simultaneous high-temperature and high-pressure studies reveal phase transformation of bulk liquid water to an ice-VII-like structure having an eight coordination. It was demonstrated through this numerical study that the observed high-temperature and high-pressure phase of water obtained upon shock compression and equilibration has high rotational diffusion and thereby the hydrogen dynamics of these crystal structures are significantly complex compared with ice VII. The current work provides new characterization methods for the numerically observed plastic crystal phase of ice at the boundary of the liquid water and ice VII phases in which the molecules have a defined lattice position but rotate freely. It is anticipated that the present work will provide important data and guide new theoretical and experimental investigations in the search for plastic crystal phases of water. The power spectra plots of bulk liquid water subjected to different temperature and pressure conditions have also been presented in this numerical study, demonstrating significant differences between these high-temperature and high-pressure shock-equilibrated phases and those of pure ice VII at 10 GPa and liquid water at ambient temperature and pressure, as well as at elevated pressures and temperatures.
