At the reporting stage in 2022, corrosion studies of carbon-containing materials were carried out under irradiation with charged particles with an energy of 2…4 MeV in an air and oxygen environment at temperatures of 400…1100°C. The effect of mode conversion on the operating characteristics of a sub-terahertz gyrotron with coupled resonators was investigated. Generalized models of nuclei have been developed and implemented in the Monte Carlo code to describe the propagation of non-classical transport of charged particles with continuous energy losses in random media. Using the developed and implemented generalized models of nuclei in the Monte Carlo code, the effects of random heterogeneity of materials on the dosimetric characteristics of the interaction of electrons and ions with them have been studied. Calculations of the effect of external force on the diffusion mobility of an ensemble of Brownian particles have been performed. Physical models for describing convective mass transfer with rigid boundary conditions in viscous incompressible media heated from below have been created, and the formation of nanoclusters in carbon dioxide during its transition to a supercritical state has been studied. The speed of movement of dispersed material in a thermo-vacuum installation has been simulated. Product Description popup.authors popup.nrat_date 2025-01-20 Close
