摘要：
In this study, two types of experimental wind turbines were tested to compare the performance at low tip speed ratio. One has a rotor with tapered blades designed by the combined blade element and momentum theory less than tip speed ratio 2. The other rotor has inversely tapered blades in which the calculated chord length are applied in an opposite way. Moreover, to analyze the behavior of the air flow around these rotors, the visualization test by PIV has also conducted. © 2011 The Japan Society of Mechanical Engineers.
