EFFECT OF PITCH ANGLE ON WIND TURBINE PERFORMANCES

Abstract

The rising cost of fossil fuels has prompted a shift towards environmentally friendly alternative energy sources, leading to an expansion in the study of renewables. Wind turbines, specially those of the small-scale variety, have emerged as a promising solution for generating sustainable electricity, particularly in rural areas and for smaller consumers. This study focuses on the analysis of pitch angles for three-bladed horizontal axis wind turbines (HAWT) with a diameter of 1.35 m, classified as micro wind turbines. The analysis assumes incompressible and viscous flow, with shear stress transport (SST) equations closed by various turbulence models. The ANSYS program was used for conducting this analysis.
