Dynamic overset 2D CFD numerical simulation of a small vertical axis wind turbine

ABSTRACT

The environmental friendly sources of power have been explored due to increased environment degradation. In this regard, wind energy may be a viable option. A renewed involvement in Vertical axis wind turbines (VAWT) was found. A wide variety of factors such as the cut-in, cut-out wind speed will decide the beneficence of VAWT as a function of energy production and reliability. In this research work, 2D computational fluid analysis of an aggregate small type of vertical axis wind turbine is performed using pecuniary codes of GAMBIT 2.3 and FLUENT 6.3. At starting, the simulation model and numerical method of small type of vertical axis wind turbine is presented in detail having classical NACA0018, NACA0021 and NACA0025 three-bladed rotor. The result shows that NACA0025 bladed rotor has the highest moment of 2.9195 Nm and power 43.7924 W at a tip speed ratio = 6.
