Equation of state and optical luminosity of benzene, polybutene, and polyethylene shocked to 210 GPa (2.1 Mbar)

Abstract: Dynamic equation-of-state data for benzene, polybutene, and polyethylene were measured in the shock pressure range 19–210 GPa using a two-stage light-gas gun. Shock-front spectral luminosities were measured for benzene and polybutene using a fast five-channel optical pyrometer. The pressure–volume Hugoniot data above 20 GPa for benzene and polybutene are in agreement with both a statistical mechanics model and a Grüneisen model for shocked hydrocarbons decomposed into a two-phase mixture of carbon in a dense d… Show more

“…On examining the SESAME 7171 polyethylene EOS, the principal Hugoniot, calculated using the Rankine-Hugoniot [3] relation (Eq. 1) based on values found in that table, deviated from experimental data [4,5]. At the time, we could not easily find any other experimental data to compare to.…”

“…Accurate knowledge of the equation of state (EOS) of the hydrocarbon ablator is essential for optimizing experimental designs to achieve desired density and temperature states in a target. Consequently, a number of planar-driven shock wave experiments have been performed on hydrocarbon materials, including polystyrene (CH) [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23], glow-discharge polymer (GDP) [24][25][26][27][28], and foams [29][30][31][32], to measure the EOS. The highest pressure achieved among these experiments is 40 Mbar [14,15], which is yet not high enough to probe the effects of Kshell ionization on the shock Hugoniot curve.…”

“…The data is for samples with an initial average density of 0.916 g/cm 3 . The later high-pressure experiments [14] were performed on samples with a higher initial average density (0.952 g/cm 3 ). Although a small difference, we adjusted for it in Fig.…”

“…We believe the results are likely to be widely applicable to other macromolecular materials. Several experimental studies of shocked PE have been reported [14][15][16][17] in addition to the quantitative data for both PE and PMP from the LASL shock handbook [18].…”
