Research Abstract

Detail velocity distribution on a wind turbine rotor is investigated experimentally. In a case of inboard, the flow on the blade have strong span-wise component. The measured surface pressure of rotor shows stronger suction pressure than that of two dimensional section tests. The boundary layer on rotor shows the laminar flow on the leading edge and it changes to turbulent at mid chord. The pressure distribution calculated from measured velocity agreed well to the measured pressure distribution.
