Experimental study on novel curved blade vertical axis wind turbines

Abstract

This paper presents the experimental study into the design and the electrical performance of a few novel curved blade vertical axis wind turbines. In the wind turbines, blade shape and quantity are crucial. In this study, curved wind blades are designed, fabricated, and used in developing the small-scale vertical axis wind turbines. Wind tunnel tests were carried out, and Results were presented for cases of vertical axis wind turbines with 2-blade, 3-blade, 4-blade configurations. Electrical parameters were monitored and compared for three different configurations. Results show that the curved blade wind turbine with a 3-blade configuration performs better when compared to the other two configurations.
