A new urban wind turbine blade design using a pressure-load inverse method

摘要

This paper presents the design methodology of a new wind turbine blade section that achieves high performance in urban environment by increasing the maximum lift. For this purpose, a turbomachine blade rows inverse design method was applied to obtain anew wind turbine blade section with constantpressure-load along the chord, at the designinlet angle. In comparison with conventionalblade designs, the new blade section has increased maximum lift, reduced leading edgesuction peak and controlled soft-stall behaviour,due to the strength reduction of the adverse pressure gradient on the blade suction surface.Wind tunnel experimental results confirmed the computational results.
