Investigation of the Transiting Test Method for the Aerodynamic Performance of Vertical Axis Wind Turbine Using Wind Generated by a Moving Vehicle

With the continuous consumption of fossil energy, environmental pollution problems have become increasingly prominent, and clean energy forms, such as wind energy, have become the focus of research in various countries. The main form of wind energy utilization is wind turbines. However, the single wind tunnel experiment method limits the experimental research on wind turbine aerodynamic performance. The proposed transiting test method using wind generated by a moving vehicle to test the aerodynamic performance of a vertical axis wind turbine (VAWT), provides a new idea for experimental research. This study uses the transiting test method to investigate the static torque and power coefficients of VAWT. Results show that under the limited conditions of the transiting test, the static torque coefficient of VAWT measured by the transiting test coincides with the wind tunnel test measurement results. The error between the static torque coefficient and the wind tunnel test results is basically less than 15%, and the error is within a reasonable range. The power coefficient of VAWT obtained through the transiting test is similar to previous research results, and the error from the wind tunnel test result is within an acceptable range. The transiting test can reproduce the research results of VAWT in the wind tunnel test and can meet the needs of the aerodynamic performance research of VAWT, which is a novel test approach for research on the aerodynamic performance of VAWT.
