摘要
Problem of obtaining data on the properties of gaseous media is considered. Gases of interest are the gases used as transport systems in technical facilities. The focus is on calculating the kinetic coefficients of gaseous medium considering the molecular processes that take place in the gas flow. Molecular dynamics method is selected as the method of modeling. Various techniques for determining the kinetic coefficients of gases are described in detail and compared. The problem is considered on the example of nitrogen flow. For this goal calculating the coefficients of self-diffusion, shear viscosity and thermal conductivity for nitrogen is made. The obtained numerical results are in good agreement with known theoretical estimates and experimental data.
