Results for Turbine B

Cl in Variable Wind Mode

This is the Cl curves at the 25% and 65% span locations along the blade are shown. The data was generated at 10 segments along the blade span, from 5% to 95%. The wind speed was varied from 7mph to 50mph to generate the angles of attack on the blade.

Lift Coefficient at 25% and 65%

Cl in Fixed Wind Mode

The predictions using the UIUC model in the above figures is from the variable wind mode. The data at 25% stations and for the full range of -180 to +180 deg is shown below for the fixed wind mode. Data generation in the fixed wind mode is used to generate input files for the PROP93 and AERODYN programs.

Cl and Cd from -180 deg to 180 deg at (r/R) = 25%

Power

Below is the power curve generated by the program with Corrigan's model, UIUC model and plain 2D data uncorrected for 3D effects. The experimental data provided by NREL for their AWT26 is also shown. The agreement between the 3D models and the experimental data is good. The modeling of turbine B is similar to the NREL AWT26 and hence the results for the two turbines are compared.
