Abstract

This paper presents the results of validation AWTSim code and this code has been used to analyze aerodynamic performance in the optimization design blade wind turbine. The validation was performed to know the accuracy of AWTSim code compared to WT_Perf by using the test wind turbine blade AWT-27. Blade AWT-27 was taken as the case for all through of this study and the design pitch angle for blade AWT-27 was 1.2° to stall (-1.2). However, in order to compare the results with available results, pitch angles 0, 1 and 2 degrees to stall were considered for simulation. The results of validation show that the predicted power curve, power coefficient and thrust by two codes are almost similar or less than 1%.
