A novel test method for the aerodynamic performance ofwind turbine airfoil using wind generated by a moving vehicle

Abstract

Refer to wind turbine airfoil wind tunnel test and consider the characteristics of wind generated by a moving vehicle, a new test method for wind turbine airfoil aerodynamic performance is proposed in this paper. Because of the relativity of motion, the vehicle will generate a relative wind field in the process of motion. Thus, the aerodynamic performance of wind turbine airfoil can be investigated using a transiting test method. In this study, a transiting test method is systematically introduced, the processing method of test data is discussed in detail, and the influence of vehicle vibration and end plate on the test results is evaluated. Three independent repeated tests are conducted, and the influence of natural wind is analyzed to eliminate the instability effect. The feasibility of the proposed test method is then verified by comparing its results with the results of wind tunnel test.
