5.4. Self-start Simulation
In Fig. 22 it can be seen a simulation of a straight blade Darrieus VAWT with 1 m blade and
0.5 m radius. Two wind turbines are compared, one with the symmetrical blade profile
NACA0012 and other with the asymmetrical blade profile NACA4412. The simulation is
done by the qBlade software [37]. For the of the VAWT start simulation the wind velocity
was set to 3
s
m
and the wind turbines TSR set to 1.
