The flow characteristics of a new hybrid vertical axis wind turbine which has advantages of the drag type and the lift type wind turbine have been investigated by the conditional sampling PIV and stereoscopic PIV The experimental apparatus is constructed using the stereoscopic PIV measurement system with a conditional sampling device and a new hybrid vertical axis wind turbine installed in a circulating water channel The value of the new hybrid vertical axis wind turbine has been clarified by the pressure distribution around the blades calculated from the velocity fields measured by the PIV Moreover, three-dimensional motions of the tip vortices of the blades have been investigated by the velocity fields measured by the stereoscopic PIV
