An initial experiment has been conducted for a
scaled down ODGV system which has the same
dimensions as the CFD model. The initial experiment is
to analyze and compare the performance of wind rotor
with and without the aid of the ODGV. In the experiment,
a custom built ODGV model is tested with the wind
blowing in 3 different directions, i.e. 0 degree, 30 degrees
and 60 degrees as shown in Fig. 3. A Wortmann
FX-63-137 5-bladed VAWT as shown in Fig. 4 was
chosen for the experiment and the experimental set up is
shown in Fig. 5.
