Intelligent Wind Power Unit with Tandem Rotors Applicable to Offshore Wind Farm: Flow and Performance Simulations of Tandem Wind Rotors

摘要

The authors have invented the superior wind power unit composed ofrnthe tandem wind rotors and the double rotational armature typerngenerator without the traditional stator. The large-sized front wind rotorrnand the small-sized rear wind rotor drive the inner and the outerrnarmatures respectively, in keeping the rotational torque counterbalanced.rnThis paper discusses numerically the flow conditions aroundrnthe wind rotors. That is, the commercial CFD code can predict well thernflow conditions and the outputs of the tandem wind rotors.
