On-Site Characterization of Automotive Diffuser Aerodynamics by 3D LPT

Race cars use aerodynamic downforce to reduce the lap times by increasing grip. Diffusers, upswept ramps located at the rear of a vehicle, are often used to enhance downforce. This investigation proposes a novel LPT facility featuring HFSB, LED illumination, and high-speed cameras to characterize the flow inside automotive diffusers. An RC car,...
