Development of a novel airfoil for low wind speed vertical axis wind turbine using QBlade simulation tool

Startup capacity is always a concern to low wind speed turbines, especially the vertical axis wind turbine (VAWT). Efforts at developing low wind speed models still persist. Hence, the focus of this study is on the development of a new airfoil for VAWT, with better startup capacity, low tip loss, an...
