Observation of Flow Asymmetry Over the Rear of Notchback Vehicles 2007-01-0900
This paper presents a series of observations of time-averaged wake asymmetry for a range of “notchback” vehicle geometries. The primary focus is on a reduced scale experiment using full-sized saloon geometry. Substantial flow asymmetry was observed in the vehicle “notch”. Similar asymmetries are reported for a full scale experiment on the same geometry along with others as diverse as production models of a luxury and mid-sized saloon; basic car shapes and a simple body. In one case a physical explanation is proposed, based on the degeneration of an unstable symmetric wake structure.
