    Estimating Chemical Conversion Rates for Composite Explosives on the Basis of Experimental Data on Pseudo-Ideal Detonation
    (2019) Ermolaev, B. S.; Shevchenko, A. A.; Dolgoborodov, A. Yu.; Maklashova, I. V.; Маклашова, Ирина Владимировна
    The conditions for the appearance of a plateau-like region called pseudo-ideal detonation in the dependence of the velocity of detonation (VOD) of composite explosives on the diameter of a charge were considered. A theoretical model of steady-state non-ideal detonation with a slightly curved front and a two-stage mechanism of chemical reaction was used for analysis. The calculations were performed for a trinitrotoluene- 50% ammonium nitrate mixture and a mechanically activated ammonium perchlorate-20% aluminum mixture. The coefficients of the equations describing the global chemical conversion rates of components were fitted in the calculations. In both cases, the dependence of the VOD on the diameter of the reciprocal charge with a plateau-like region was obtained for an increasing conversion rate of the major explosive (trinitrotoluene and ammonium perchlorate, respectively).

    Radial Distribution Functions for Molecules in the Universal Equation of State Model for Gaseous/Fluid/Condensed Systems
    (2019) Bogdanova, Y. A.; Gubin, S. A.; Maklashova, I. V.; Богданова, Юлия Андреевна; Губин, Сергей Александрович; Маклашова, Ирина Владимировна
    © 2019, Pleiades Publishing, Ltd.Analytical expressions and a numerical method for calculation of distribution functions of hard spheres gij(r) based on inverting the Laplace transform for functions rgij(r) obtained from the Percus—Yevick equation are obtained. The method for calculation of radial distribution functions is applicable for any distances between hard spheres; it is verified by comparison of numerical results and Monte Carlo simulations. The application of the developed method for calculation of the radial distribution functions of metal atoms is demonstrated. Distribution functions are required to construct a universal theoretical model of equation of state capable of describing both dense multicomponent gas and condensed substances (liquid or solid phases) with high accuracy which is substantially faster than computer experiments (Monte Carlo and molecular dynamics methods).
