In the present work, a semi-empirical algorithm is proposed for estimating the adiabatic coefficient (γ), the isothermal compressibility (κτ), the heat capacity at constant pressure (cp), and constant volume (cv), for liquid mixtures of organic compounds as a function of temperature and concentration. The algorithm was applied to the binary systems: 1,6-Dichlorohexene (x) + Dodecane (1-x) and 1,5-Dichloropentane (x) + Dodecane (1-x) reported in literature. The obtaining values for γ, cp, cv and κτ are reported at all concentrations and temperatures. The implementation of the algorithm required experimental data of the adiabatic coefficients of the pure components (γi0) to 298.15 K, acoustic and volumetric data of the binary mixture in the entire concentration and temperature range between (278.15–328.15) K every 5 K. The results obtained are in excellent agreement with the experimental results.

A new formula is proposed for predicting the Gurney velocity () of pure, mixed, and aluminized high explosives at any initial density. The simple relationship uses the detonation pressure and adiabatic coefficient calculated via the BKW code using the 1,3,5-Trinitro-1,3,5-triazacyclohexane (RDX) set of parameters. For 27 explosive compositions,was estimated using both the new formula and three older ones, and the results of each were then compared to experimental values. It is found that the new relationship is more accurate than older ones for predicting the Gurney velocity of aluminized compositions. The root mean square (rms) deviation of the new formula is 0.04–0.05 km/s for all tested explosives. [ABSTRACT FROM PUBLISHER]

[Display omitted] In the present work, a semi-empirical algorithm is proposed for estimating the adiabatic coefficient (γ), the isothermal compressibility (κ τ), the heat capacity at constant pressure (c p), and constant volume (c v), for liquid mixtures of organic compounds as a function of temperature and concentration. The algorithm was applied to the binary systems: 1,6-Dichlorohexene (x) + Dodecane (1-x) and 1,5-Dichloropentane (x) + Dodecane (1-x) reported in literature. The obtaining values for γ , c p , c v and κ τ are reported at all concentrations and temperatures. The implementation of the algorithm required experimental data of the adiabatic coefficients of the pure components (γ i 0) to 298.15 K, acoustic and volumetric data of the binary mixture in the entire concentration and temperature range between (278.15–328.15) K every 5 K. The results obtained are in excellent agreement with the experimental results. [ABSTRACT FROM AUTHOR]
