NREL Phase IV wind turbine
Example simulation of a wind turbine
The NREL Phase IV wind turbine has two blades with NREL S809 airfoil featuring non-linear twist and linear taper. The turbine radius is
m and the aspect ratio is
. This case considers the turbine with a collective pitch of
deg, rotating at
rpm, at a freestream velocity of
m/s. A structured mesh with 15 elements in the chordwise and 32 elements in the spanwise direction (for each blade) is used. The results are obtained with an azimuthal step of
deg (
s) for 3 revolutions. The image below shows the pressure coefficient distribution.
The animation below shows the development of the wake.
