“…Despite various approximate models have been used for the structural optimization of fans, most of the studies have clear objectives, and the studied structures are single-stage blades with fewer influencing factors (Venturelli and Benini, 2016;Chai et al, 2020;Taghinezhad et al, 2021). In addition, sensitivity analysis is rarely performed.…”

Large axial fans are widely used in industrial refrigeration, building ventilation, and other scenarios because they have inlet guide vanes (IGVs) and outlet guide vanes (OGVs) to make their operation economical and efficient. However, unreasonable guide vane structure is prone to flow separation, forming a tail vortex and interfering with other blades, thereby resulting in the deterioration of working conditions and large noise. Taking a large axial fan with both IGVs and OGVs as the research object, this paper analyzed the structural variables of the fan by global sensitivity analysis method and determine the target of settings optimization as IGV according to the analysis results and the internal flow characteristics of the fan. Furthermore, IGV was parametrically designed, and Kriging model was established and optimized by the second non-dominated sorting genetic algorithm (NSGA-II). Eventually, total pressure and sound pressure level (SPL) were used as targets for multi-objective optimization. The results indicated that the noise produced by the optimized fan was reduced by 6.4 dB and total pressure was increased by 156.4 Pa, with an increase of 0.86% in the total pressure efficiency at the rated working condition, which proved the reliability of the proposed method. This paper also provides a valuable reference for the optimization of similar fluid equipment.

Due to the increase in electricity consumption in the world, the tendency to increase resource diversity in the electricity generation section has increased. With the decrease in the reserves of petroleum and derivative products used in traditional energy production systems, energy production has turned to renewable energy sources. Examples of renewable energy sources are the sun, wind turbines, and fuel cells. In order to provide sustainable energy production in wind turbines, the blades and body must be protected. In this study, the blade pitch angle control of the wind turbine is realized with the PID controller and the wind turbine is protected from high speeds. The coefficient control of the PID controller is determined by the PSO (Particle Swarm Optimization) and Ziegler Nichols method. Simulation was carried out in MATLAB/Simulink environment. It has been observed that the PID coefficient parameters optimized with PSO in the pitch angle control process reach the reference power value in a shorter time compared to the PID parameter values calculated with Ziegler Nichols. In addition, it was observed that the oscillation value was less at the reference power reached and the pitch angle increased.
