- ПубликацияОткрытый доступThe influence of type of the intermolecular interaction potential on transport properties of helium(2020) Amir, Zh. A.; Bogdanova, Yu. A.; Maklashova, I. V.; Gubin, S. A.; Богданова, Юлия Андреевна; Маклашова, Ирина Владимировна; Губин, Сергей Александрович© Published under licence by IOP Publishing Ltd.A method for calculating the transport properties of helium based on the results of thermodynamic modeling using a theoretically equation of state obtained using perturbation theory is presented. The influence of the type of interparticle interaction potential on the accuracy of calculating the helium's viscosity and thermal conductivity is shown in comparison with the known experimental data.
- ПубликацияОткрытый доступMolecular dynamics simulation of polymerization of the carbon under thermal decomposition of methane at constant volume(2020) Kudinov, A. V.; Gubin, S. A.; Bogdanova, Yu. A.; Губин, Сергей Александрович; Богданова, Юлия Андреевна© Published under licence by IOP Publishing Ltd.Thermal decomposition of methane was simulated at high temperature and pressure using the molecular dynamics method. The calculation was carried out employing ReaxFFlg potential. We show the dependence of the decomposition products on time and the results of methane polymerization at constant temperature. We also show the influence of gradual temperature decrease at the size of the polymers.
- ПубликацияОткрытый доступComparison of molecular dynamics simulation methods of methane shockwave compression(2020) Kudinov, A. V.; Gubin, S. A.; Bogdanova, Yu. A.; Губин, Сергей Александрович; Богданова, Юлия Андреевна© Published under licence by IOP Publishing Ltd.Shockwave compression of methane was simulated using the molecular dynamics method with Hugoniostat and MSST approach. The calculation was carried out employing ReaxFFlg potential. We show comparison of simulated Hugoniots for pressure range 0,1-44 GPa and times required for simulation run of two different methods. We also compare two ReaxFF potentials: ReaxFF(2008) and ReaxFF-lg.
- ПубликацияОткрытый доступApplication of the perturbation theory for the calculation of thermodynamic and transport properties of hydrogen and its isotopes(2020) Bogdanova, Yu. A.; Maklashova, I. V.; Gubin, S. A.; Vagina, U. D.; Богданова, Юлия Андреевна; Маклашова, Ирина Владимировна; Губин, Сергей Александрович© 2020 Published under licence by IOP Publishing Ltd.In this paper, we analyzed the analytical relationships in the literature to calculate the viscosity coefficient obtained from the Chapman-Enskog kinetic theory using the Lennard-Jones pair interaction potential. In the proposed formulas for calculating the viscosity of individual substances, there are values of the radial distribution function and the hard-sphere diameter. These quantities were obtained using a technique developed previously by the authors based on the perturbation theory used to calculate the thermophysical properties of substances
