The paper is dedicated to development of log of the ANSYS FLUENT program text commands. Although this program has well-developed and easy-to use graphical interface, command logs allow to conduct the configurations of the solver, optimizing the process of calculation justification safety of reactor experiments conducted at the “Institute of Atomic Energy” Branch of the RSE “National Nuclear Center of the Republic of Kazakhstan” (IAE Branch RSE NNC RK). Command logs allows to control the command to save the ANSYS FLUENT program solver as code in a separate file, which can later be used for other calculations. Command log allows to save settings the ANSYS FLUENT program solver as program code in a separate file, which can later be redacted and used for other calculations. Also, this would enable improving the group work of employees above one project, facilitate the exchange process of solver parameters and promptly make amendments and corrections. In the framework of this work, a technique for constructing a command log was developed for modeling thermophysical state of experimental devices in reactor experiments. The developed technique was tested on the example of solving a thermophysical task with a typical ED.

“…In this work, the authors used the k-ε turbulence model with two equations, which provides a general description of turbulence with two transport equations for the turbulent kinetic energy k and the turbulent energy dissipation rate ε [18,19]. Essentially, the magnitude and direction of the aerodynamic forces on the sail depend on its position relative to the airflow, which is characterised by the attack angle [20][21][22][23][24].…”

The authors of the work numerically studied the aerodynamic coefficients of the sail blade, during which the patterns of three-dimensional flow around airflow and the pressure distribution field were obtained. The triangular sail blade is used as the power element of wind turbines. The sail blade modeling was based on the Reynolds-averaged Navier–Stokes equations (RANS) using the ANSYS FLUENT computer program. A flow pattern is obtained, which gives a physical explanation of the nature of the airflow around the sail blade and the pressure distribution field. Comparative analyses of theory and experiment are given. In the range of Reynolds numbers from 0.5 × 104 to 2.5 × 104, the change in the drag force coefficient is from 1.04 to 0.54, and the difference in the lift force coefficient is from 0.52 to 0.33.

For more than a hundred years, wind turbines have been used to convert the potential of wind energy into electricity. In recent years, a trend has emerged in the form of a sharp increase in fossil fuel prices, as a result of which the development and production of wind turbines has greatly increased. The market for wind turbines is broad; however, in general, many of them are designed for relatively high wind speeds, typically from 10 to 15 m/s at low power. Central Asia is known for lower wind speeds, so the commercial wind turbines do not meet the energy demand. Against this background, the current topic is the development and research of wind turbines and their functional elements for low wind speeds, among whose representatives is the sail. The authors of the paper numerically studied the aerodynamic coefficients of the sail blade, determining the patterns of three-dimensional air flow around it and the pressure distribution field. The sail blade was modeled using the computer program ANSYS FLUENT based on the Reynolds-averaged (RANS) Navier-Stokes equations. The inflow velocity varied from 3 to 15 m/s. Comparative analyzes of the theoretical and experimental results are given. The patterns of changes in aerodynamic parameters determined by the authors could contribute to the understanding of the complex aerodynamic patterns of a turbulent flow around the blades.
