Effect of nanodisperse powders on the spreading and crystallization of a metal drop on a porous substrate
Autor: A N Cherepanov, V K Cherepanova, V V Bublik
Publikováno v: Journal of physics. Condensed matter : an Institute of Physics journal. 34(34)
The influence of modifying nanopowders on the spreading and crystallization of a nickel droplet on a porous steel substrate is analyzed. For this purpose, a model has been developed for the spreading of a drop of liquid metal after its high-speed col

A mathematical model of scandium ore deposit formation in liquating magmatic melts
Autor: A. N. Cherepanov, V. K. Cherepanova
Publikováno v: Thermophysics and Aeromechanics. 24:309-322
Solidification of liquating silicate magmatic melts may lead to formation of rare earth mineral deposits. By the example of quasi-binary system SiO2–Sc2O3, the processes of cooling and directional solidification of the melt in an intrusive chamber

Modeling the dynamics of sublimation of fractured rocks in the lithospheric mantle wedge beneath volcanoes of the Avacha group (Kamchatka)
Autor: G. V. Kuznetsov, V. P. Logachev, V. K. Cherepanova, A. N. Cherepanov, V. N. Sharapov
Publikováno v: Geochemistry International. 55:231-250
A quantitative analysis of sublimation of intensely fractured rocks in the mantle wedge was performed using a model of planar fracture channel. The use of dimensionless variables allowed us to analyze the influence of the Nusselt and Sherwood criteri

Nucleation of a solid phase on spherical refractory nanoparticles
Autor: V. K. Cherepanova, A. N. Cherepanov
Publikováno v: HIGH-ENERGY PROCESSES IN CONDENSED MATTER (HEPCM 2019): Proceedings of the XXVI Conference on High-Energy Processes in Condensed Matter, dedicated to the 150th anniversary of the birth of S.A. Chaplygin.
The mathematical model of the heterogeneous nucleation of a solid phase on a wetted spherical nanosubstrates is developed on the basis of the thermodynamic approach. According to the proposed model, new expressions for the nucleation energy and the n

Dynamics of changes in the physical characteristics of a hydrothermally altered geological section according to nonisothermal physicochemical simulation (the Mutnovsky Volcano)
Autor: A. Ya. Shevko, K. V. Chudnenko, V. K. Cherepanova, M. P. Gora, E. P. Bessonova
Publikováno v: Izvestiya, Physics of the Solid Earth. 47:519-530
The paper presents the results of numerical simulation of a subaerial volcanic hydrothermal system. The model is based on the factual data on the rock composition and the geological structure of the Mutnovsky Volcano. We develop a new approach to con

Thermo- and hydrodynamic processes at the evolution of fluid systems
Autor: V. K. Cherepanova
Publikováno v: Thermophysics and Aeromechanics. 17:193-203
The dynamics of phase fronts in a hydrothermal solution filtering through the fluid-conductor pores upwards to the earth surface was investigated on the basis of the model of volcanogenic orthomagmatic fluid systems. The problem was solved with regar

On the dynamics of the rhythmic crystallization of magmatic bodies during the directional solidification of cotectic melts
Autor: V. K. Cherepanova, S. I. Plaksin, A. N. Cherepanov, V. N. Sharapov
Publikováno v: Geochemistry International. 47:454-462
A problem on the directional crystallization of melt was solved taking into account heat and mass exchange between the two-phase zone and the cooling volume of a magmatic body. Conditions were determined for the development of rhythmic crystallizatio
