Research on the Aerodynamic Noise Mechanism and Noise Reduction of SUV Roof Hollow Spoiler

The development of a hollow spoiler not only focuses on aerodynamic drag performance and pollutant management performance, but also on achieving aerodynamic noise and low noise performance. The aerodynamic noise characteristics of the hollow spoiler under good wind resistance performance and polluta...
