The optimal profile of wind generator blade modelling with CFD-method

Abstract

Using of renewable energy sources, instead of traditional oil, gas and coal, is the one of the ways by which it’s possible to hold global warming mechanisms. One of these sources is the wind energy and the device-transformer for it is the wind generator. This paper deals with the problem of the optimal wind generator blade design which allows getting the device efficiency maximum. The alternative wind generators realisations and their advantages are showed in the work. The numerical methods for fluid dynamic equations solving were applied for the optimal profile definition. The advantages of this way were showed, also the model, which was the best fitted for the concerned conditions, was chosen. Modelling was realized in ANSYS Fluent. The results were compared with the real wind generations data.

Optimization of the blade profile of a vertical axis wind turbine based on aerodynamic analysis

“…The study of the aerodynamic properties of the blades is an important task in the development of wind power plants, [1]. Understanding the shape and characteristics of the blades as they rotate allows you to optimize the efficiency and reliability of power plants, as well as reduce the negative impact on the environment [2].…”
