Abstract
An automobile diffuser is the upwardly-ramped surface at the rear of the vehicle's underbody. Aerodynamic downforce and drag are generated as airflow travels underneath and along the ramped surface of the diffuser. However, with a moderate drag penalty, the downforce-producing effect of the diffuser can be further enhanced by an arrangement of aerodynamic devices along the ramp surface and within the diverging flow channel of the vehicle's diffuser.
Claims8
A vehicle underbody diffuser to enhance aerodynamic downforce;
- consisting of a single flow channel or a subdivided flow channel located at a rear of an automobile, the said diffuser including:
- A convex-shaped bump attached on a diffuser ramp surface across a span of the diffuser flow channel and at a location close to an exit of the diffuser flow channel.
- An inverted wing with a pressure surface as atop surface and a suction surface as the bottom surface positioned laterally across a span of the diffuser flow channel and underneath the convex-shaped bump with a chord length of the wing parallel to the length of the bump.
