THE AERODYNAMICS ANALYSIS OF AIRFOILS FOR HORIZONTAL AXIS WIND TURBINE BLADE USING COMPUTATIONAL FLUID DYNAMIC
ABSTRACT: This paper
included in designing
and simulating for
2D. It may
use two software's
called Gambit and FLUENT
to generate the
data from the
fluid flow cases.
In this research
select two models
NACA airfoil NACA4412 and NACA4415.
Chose NACA 4412 because lift coefficient is higher than NACA4415. In this study computational
flow over an
airfoil at different
angles of attack
(0º, 5º,10º,15º ,20º)
using CFD (Computational fluid
dynamics) simulation two dimensional
airfoil NACA 4412
and NACA4415 CFD models are presented using ANSYS-FLUENT software. For
this model Using turbulent viscosity
k-epsilon (standard wall function)
near the wall
and wind velocity
5 m/s Here,
NACA 4412 airfoil
profile is considered for analysis of wind turbine blade. Geometry of airfoil is created using
GAMBIT 2.4.6 and CFD analysis is carried out using FLUENT 6.3.26 at
various angles of
attack from 0º
to 20º. Lift and Drag forces along
with the angle
of attack are
the important parameters
in a wind
turbine system. The
Lift and Drag forces are
calculated at different sections for angle of attack from 0o to 20o for low
Reynolds number. The analysis showed
that the angle
of attack of 10o has
high Lift/Drag ratio.
The airfoil NACA
4412 is analyzed based
on computational fluid
dynamics to identify
its suitability for
its application and
good agreement is made between the results.
