Research on energy-saving wind turbine blade based on advanced fluid mechanics technology

Abstract

The aerodynamic performance of wind turbine blades is of great significance and value to the power output of wind turbines. Correct evaluation of blade performance is beneficial to the design and design of wind turbines. In the operating environment, the aerodynamic load on the blade is a combination of the aerodynamic pressure of the air and the additional force generated by its own rotation. Under different environmental conditions, the aerodynamic load on the wind turbine blades will be significantly different. Using advanced fluid mechanics, the developed program is used to perform aerodynamic simulation on a certain type of wind turbine blade calculation example to obtain the flow field and blade surface pressure coefficient distribution. The calculated results are in good agreement with the experiment, and the developed program can be used for aerodynamic analysis of engineering wind turbine blades, which is conducive to the development of wind turbine design.
