Abstract

Although
there are many blade profile have been improved for use in aviation and energy
sector, there is still needed blade profiles which have higher performance
especially the commercial horizontal axis wind turbine efficiency is taken into
account. The purpose of this study is to obtain the new blade profiles which
have higher lift (CL) and drag (CD) coefficients for wind turbine making
geometric modifications on several NACA wing profile systematically. For this
purpose, the performance of NACA and developed new profiles have been compared
with each other using computational fluid dynamics analysis and it is seen that
the new developed profiles have higher performance than NACA profiles. Later
on, according to the Blade Element Momentum Theory (BEM Theory) turbine blades
are designed with developed new profiles and 3-dimensional CFD analyses are
performed. Increase in torque in the wind turbine is determined.
