The Analysis of Wind Turbine with Horizontal Rotation Axis with the Use of Numerical Fluid Mechanics

The analysis of horizontal rotation axis wind turbine of type H-rotor is presented in this article. The calculation has been made using a 3D model of horizontal rotation axis turbine for three wind flow speeds: 5, 10, 15 m/s, with the stable rotational speed of the rotor of 200 rotations per minute. The analysis of wind turbines requires building a 3D calculation model. The building of such a model is very time-consuming and the calculations involving numerical fluid mechanics require substantial calculation power. The article presents 3D CAD model of horizontal rotation axis wind turbine in ANSYS calculation environment, discrete net, and boundary conditions and the results of calculating horizontal rotation axis wind turbine with the use of numeric fluid mechanics.
