INTRODUCTION OF THE
• This Project aims to undertake aerodynamic analysis of a
Horizontal Axis Wind Turbine
• Computational Fluid Dynamics (CFD) software is used to
compare the performance of different Wind Turbine Blade
• A steady state, incompressible flow solver for Multiple
Reference Frames (MRF)
• Flow optimization in different blade sections, with different Angle of
• Geometry of the standard NACA-9417 Airfoil
• MH-102 from -Illinois University
• SC 02-0714 - Airfoil Investigation Website
• Flow optimization in a blade with a add-on part which gives better result
• Flow of air over a rotating wind turbine rotor implies that the fluid flows
in an inertial frame of reference while the rotor rotates in a non inertial
BLADES WITH DIFFERENT
• After completion of first cut analysis, we
finalized NACA-9417 at 10 degree angle of
attack is giving the better results
• The blade which we got the better result , in
that the add-on part(winglet) will be
implemented and the second cut analysis starts
in that configuration
• A growing number of researchers is using CFD to
study wind-turbine wake aerodynamics
• More research on the effect of stratification on power
production is to be expected
• Aerodynamics turbulence is a dominating factor,
affecting the blade performance and Wake behaviour
so we tried to reduce this factor in this analysis
