Vehicle component comprising a flow guiding element

摘要

A vehicle component includes a surface which, during operation, is exposed to an air flow. The surface includes a separating area where the air flow separates from the surface, and at least one obstructing element associated with the separating area for introducing an obstruction into the air flow. 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.

1. A vehicle component for a vehicle, in particular a rail vehicle for high-speed traffic, comprising:
a surface which, during operation, is exposed to a relative wind-induced air flow having a local main flow direction, wherein said surface has a flow separation edge at which said air flow separates from said surface, and at least one perturbing element located in the region of said flow separation edge is provided, which is formed in order to introduce a perturbation into said air flow, wherein said perturbing element has at least one guide face protruding into said air flow, wherein said guide face being formed, and inclined by an inclination angle with respect to said local main flow direction, in such a way that a velocity component, which is oriented transversely with respect to said local main flow direction and which induces local turbulence in a shear layer of said air flow separating from said surface downstream of said perturbing element at said flow separation edge, is imposed to said part of said air flow striking said guide face.
