20130239844 | Vehicle Component Having a Recess with air flowing over it - A vehicle component includes first and second surfaces, in a first travel direction of the vehicle. The first surface is exposed to an air flow having a local main flow direction. In a region of a recess on the vehicle, the first surface forms a flow separation edge where the air flow is deflected from the first surface. The recess is delimited by a leading first wall facing the local main flow direction and a trailing second wall. The flow separation edge extends transversely to the local main flow direction over a majority of a transverse dimension of the recess. In the local main flow direction, the second surface borders on the flow separation edge and forms a part of the first wall. The second surface is disposed so that it is inclined like a chamfer about an acute angle of inclination relative to the local main flow direction. | 09-19-2013 |
20130291758 | Vehicle Head - A superstructure module of a front-end section of a vehicle is supported on a chassis and includes a flow guiding device. The front-end section forms a leading, free vehicle end during normal operation of the vehicle. The flow guiding device is mounted on a lower side of the superstructure in the longitudinal direction of the vehicle between the free vehicle end and a leading end of a chassis. The flow guiding device influences air flow that flows during operation of the vehicle along the lower side of the superstructure from the free vehicle end to the chassis section. The flow guiding device via a deflection area confers on the air flow, in the region of a flow separation edge at the leading end of the chassis section, a downwardly directed direction of flow. | 11-07-2013 |

The obstructing element includes at least one guide surface which protrudes into the air flow. The guide surface is inclined relative to the local direction of the main air flow so that it confers on the part of the main air flow that impacts the guide surface a speed component that runs perpendicular to the local direction of the main air flow and induces turbulence in the air flow downstream of the obstructing element. | 11-07-2013 |
