Abstract

The aim of this study was a comparative analysis of the suitability of the use of airfoil for wind power. Based on numerical analyses and analytical methods, information on the power factor was obtained. The analyses were carried out for the wind turbine blades and rotors of a vertical axis wind turbine. The tests were performed for the constructed profile and compared with the profile DU 06-W-200 used in the construction of a wind turbine rotors. A vertical axis wind turbine model equipped with designed blade profiles was prepared. The main predicted purpose of the device is to supply electricity to the household. The blade profile models were prepared and then a numerical analysis was performed using the CFD application. The obtained results for given wind speeds and types of profiles were compared with each other. The conducted research allowed to determine the sense of applying the unaudited profile based on the determined value of wind turbine power coefficient. Studies have shown that the accurate preparation of the optimal rotor blade with respect to flow of air stream strongly influences the characteristics of the wind turbine.

Highlights

One of the most important issues appearing in the power energy sector is development and examining of modern technologies enabling maximization of obtaining energy from renewable sources
A model of a wind turbine with a vertical axis of rotation was developed with the use of new profiles
Based on the numerical analysis, it can be concluded that the new profile achieves comparable or even better results than the comparative profile in relation to the aerodynamics itself and the value of wind power used by the turbine

Summary

Introduction

One of the most important issues appearing in the power energy sector is development and examining of modern technologies enabling maximization of obtaining energy from renewable sources. The development of appropriate technology to intensify the use of renewable energy sources in this context is very important [4]. Wind power plants, are most often associated with large high masts and turbines with blades of an enormous span. This is not the only solution for wind turbines. The result is the construction and continuous development of vertical axis wind turbines. Technology of wind turbines with a vertical axis of rotation is a technology that tries to convince investors to back to that idea.
