“…The Hugoniot (traditional shock data obtained from refs − can also be found on the worldwide Web shock database at ) EOS for pure water and pure ethanol were first measured in 1956 by Walsh and Rice and have been well documented and studied since then. − However, Hugoniot EOS data for binary mixtures of water and ethanol do not exist in the literature. Unshocked mixtures of water and ethanol have been extensively studied, due to the nonideality and anomalous thermodynamic properties of the mixture. − Of particular interest is the nonmonotonic trend in sound speed through the mixtures from pure water to pure ethanol; there is a maximum sound speed at ethanol mole fraction χ ethanol = 15%, as seen in Figure .…”

“…However, the predictions of the ULH do not account for the influences of intermolecular forces, such as hydrogen bonding, which play a dominant role in mixing. Thus, for certain liquids, such as water, and for nonideal liquid mixtures, deviations from the ULH are commonly observed. − Nevertheless, deviations from the ULH have yet to be fully understood, but the magnitude and direction of the deviation are expected to provide meaningful insight into the dynamic effects of intermolecular forces.…”

Laser shock Hugoniot data were obtained using ultrafast dynamic ellipsometry (UDE) for both nonideal (ethanol/water solutions with mole percent χ(ethanol) = 0%, 3.4%, 5.4%, 7.5%, 9.7%, 11%, 18%, 33%, 56%, 100%) and ideal liquid mixtures (toluene/fluorobenzene solutions with mole percent χ(toluene) = 0%, 26.0%, 49.1%, 74.9%, 100%). The shock and particle velocities obtained from the UDE data were compared to the universal liquid Hugoniot (ULH) and to literature shock (plate impact) data where available. It was found that the water UDE data fit to a ULH-form equation suggests an intercept of 1.32 km/s, lower than the literature ambient sound speed in water of 1.495 km/s (Mijakovic et al. J. Mol. Liq. 2011, 164, 66-73). Similarly, the ethanol UDE data fit to a ULH-form equation suggests an intercept of 1.45 km/s, which lies above the literature ambient sound speed in ethanol of 1.14 km/s. Both the literature plate impact and UDE Hugoniot data lie below the ULH for water. Likewise, the literature plate impact and UDE Hugoniot data lie above the ULH for ethanol. The UDE Hugoniot data for the mixtures of water and ethanol cross the predictions of the ULH near the same concentration where the sound speed reaches a maximum. In contrast, the UDE data from the ideal liquids and their mixtures are well behaved and agree with ULH predictions across the concentration range. The deviations of the nonideal ethanol/water data from the ULH suggest that complex hydrogen bonding networks in ethanol/water mixtures alter the compressibility of the mixture.

Abstract. The results of numerical experiments on modeling of shock wave loading of mixtures are obtained by using thermodynamic equilibrium model TEC (thermodynamic equilibrium components) are presented. The thermodynamic parameters are modeled for the mixtures that include epoxy resin as a component. The model allows taking into account the phase transition under shock wave loading, when the substance in the region of phase transition is considered as mixture of low-pressure phase and high-pressure phase. Interest in the investigation of compressibility of such mixtures is associated as with the possibility of creating materials that have the required properties and the properties of the materials themselves. The good agreement of these model calculations with the data of different authors that defined on the experiments basis is obtained. The model allows to describe dynamic loading of solid and porous mixtures comprising epoxy resin and various components such as quartz SiO2, periclase MgO, corundum Al2O3, spinel MgAl2O4, enstatite Mg2[Si2O6]. IntroductionThe investigations of thermodynamics parameters of porous materials including, in particular, the solid organic substances under shock-wave loading are of interest in many problems of modern science; in this regard new models appear for the description of the behavior of such materials, for example [1][2][3][4][5][6][7][8]. These investigations are important in solving the applied problems of dynamic compaction, shock-wave synthesis, and other explosive technologies.Interest in the study of compressibility of mixtures comprising as component epoxy resin due to their properties [9,10]. The composite materials combining the properties of the components are created on base on these mixtures. Epoxy resins are characterized by high resistance to the action of halogens, some acids, alkalis; they also have high adhesion to metals. Additional properties of the composite materials are obtained by using various additives to the mixture. For example, quartz SiO 2 is widely used in optical and electronic devices, in the manufacture of silica refractories and quartz glass. An additional important property of quartz is the existence of polymorphic phase transition under shock wave impact. Substantial change in the volume of such components included in the mixtures allows expanding the range of changes of thermodynamic parameters of the mixtures under shock wave loading. Periclase MgO is important component of magnesite and dolomite refractory. Abrasive materials are produce from corundum Al 2 O 3 . Spinel MgAl 2 O 4 is rare mineral of cubic crystal structure. It is a mixed oxide of magnesium and aluminum (volumetric fraction MgO 28.2%; Al 2 O 3 71.8%). The name of mineral enstatite Mg 2 [Si 2 O 6 ] is derived from the Greek words ενστ ατ ης (enstates) "the enemy", "the resistance",
