In this paper, the authors performed a series of numerical analysis using CFD methods for the study of turbulence intensity effects on the efficiency of a wind turbine vertical axis Darrieus type, at the starting point. These analyzes have the tip speed ratio value (TSR) equal to 1. The solver used is based on pressure and it uses the Simple Method (semi-implicitmethod-pressure-linked-equation). To determine the influence of the turbulence intensity were imposed on border conditions, the intensity values between 1 and 20%. Finally, are represented variations of moment and power coefficients for a full rotation (0-360 degrees). The magnitude vorticity variation is also presented for all the studied cases.
