“…It is assumed that the high-speed airflow in the rotor is a compressible viscous flow, and the gas flow field is a turbulent model. [12][13][14] The flow satisfies the mass conservation equation and momentum conservation equation. [15][16][17] The mass conservation differential equation is given as…”

The task of the fiber transport channel (FTC) is to transport the fibers from the carding roller to the rotor. Its geometric position in the spinning machine has a strong influence on the characteristics of the airflow field and the trajectory of the fiber motion in both the rotor and the FTC. In this paper, a three-dimensional pumping rotor spinning channel model was established using ANSYS-ICEM-CFD software with three different positions of the FTC (positions a–c). Further, the simulations of air distribution were performed using Fluent software. In addition, the discrete phase model was used to fit the fiber motion trajectory in the rotor. The simulation results showed that among the three types of FTC, position b is the optimal condition. The gradients of airflow velocity in the channel at position b were greater than those of the other two positions, which is conducive to straightening of the fiber.

“…It involves solving a hierarchy of flow equations that introduce new apparent stresses known as Reynolds [16,17]. 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.
