Wind turbine
model
The wind turbine model used in this study is the NREL PHASE VI wind
turbine [21]. It is a wind turbine designed by NREL (National
Renewable Energy Laboratory). It uses S809 airfoil from root to tip.it
is also twisted along the span. The cross-sections of airfoil along the
blade length which is accompanied by chord and twist distributions, are
shown in Figure 1 and figure 2. The 3d geometry model is established
using Ansys Fluent [22] is presented in figure 3 and the
corresponding airfoil is shown in figure 4.Technical parameters of the
blade is shown in table 1
