Abstract |
|
In present work, a Vertical Axis Wind Turbine (VAWT) Darrieus type having NACA 4422 blade is designed for low wind speed. For calculating coefficient of power at different tip speed ratios Double Multiple Stream Tube (DMST) model is used. Then the 2D model of VAWT is prepared and CFD analysis is performed for the same. Results of DMST model is compared with CFD analysis of VAWT. CFD is a great tool to analyze the performance of wind turbine. Using both methods an optimum tip speed ratio for designed VAWT is found, as it is one of the most important factor affecting power generation of VAWT. Both in DMST model and CFD analysis maximum power was generated at tip speed ratio of 2. |
