Performance Analysis of Vawt Based on the Number of Blades and Pitch Angle Using Matlab

EasyChair Preprint 15837

Abstract

This paper aims to determine the performance of VAWT based on the number of blades and pitch angle. The number of blades used are 2, 3, 4 and the pitch angles used are 0, 5, 10, 15, 20 degrees. Numerical analysis is carried out through the MATLAB application to determine the value of TSR, coefficient power, and turbine power. This paper will also show a graph of the relationship between TSR, coefficient power, and turbine power. The results of this study indicate that a VAWT with 2 blades at a pitch angle of 0 degrees has the highest efficiency of 0.4016 or 40%, which is the maximum limit of turbine efficiency of 16/27 or 59.3%. However, 2 blades are less stable at other pitch angles than 3 and 4 blades.

Keyphrases: Coefficient Power, TSR, Turbine Power, VAWT
