Outline of Final Research Achievements |
A three-dimensional aerodynamic design method for the wind-lens turbine has been developed, which consists of the meridional viscous flow analysis and the two-dimensional blade element design. A multi-objective optimal design approach for the wind-lens and the rotor blade has been constructed by combining the present aerodynamic design method for the wind-lens turbine and the genetic algorithm (GA). The present optimal design approach can achieve the simultaneous optimization of the rotor blade loading distribution and the wind-lens shape. The aerodynamic performance and the flow field for a Pareto optimal solution of wind-lens turbines designed by the present optimal design approach has been investigated by wind-tunnel tests and three-dimensional Reynolds averaged Navier-Stokes (RANS) simulations. It was found that the wind-lens turbine can realize the transcendence of the theoretical Betz limit with the present optimal design.
