Investigation of Blade Profiles of Vertical Axis Wind Turbine by Numerical Simulation
1Ritsumeikan University, Kusatsu City, Shiga, Japan
There are two types of vertical axis wind turbine, drag-type and lift-type. Drag type wind turbine can rotate in low speed wind condition, although its rotation speed is low. Lift type wind turbine can rotate at higher speed, although it works only in high speed wind condition. This study investigates new blade profile that realize rotation in low wind speed condition and higher rotation speed by numerical simulation.
