Effect of blade pitch angle on the aerodynamic characteristics of a twisted blade horizontal axis wind turbine based on numerical simulations

The present work includes a study of the impact varying pitch angles and angular velocity on performance parameters horizontal axis wind turbine using computational fluid dynamics. Simulations have been made commercial Ansys 15 software. Seven are chosen for study, i.e., 0° , 5 ° 10° 15° 20° 25° 28°, two values 1.57 rad/sec 2.22 used simulation. turbulence model is shear stress transport (SST) K-?. A detailed influence angle aerodynamic characteristics highlighted. Performance like torque power found to exhibit random variability with change in angle. verification dynamics (CFD) standard empirical formula best noted coefficient.
