The angle is adjusted in radians and seems to indicate a maximum value at approximately 0.62 radians, or roughly 35.5 degrees. This translates in a maximum conversion of 38.5% of the wind force into rotational motion. Therefore, the blades should be tilted at an angle of roughly 35.5 degrees from the oncoming air stream to obtain the optimal amount of energy using flat blade windmills.

A computational fluid dynamic (CFD) analysis was intended for this blade angle to investigate the pressure distribution and airflow as it passes the blades. Unfortunately, the license for the CFD software, Fluent, has expired. The meshed model of the blade design, using the program Gambit, has been included below.

The completed CFD analysis will be posted once access to Fluent or an equivalent software program becomes available.<br>
