    • n bargeboard In architecture, a board placed in advance of a gable and underneath the barge-course, where the roof extends over the wall, either covering the rafter that would otherwise be visible, or occupying its place. The earliest barge-boards date from the fourteenth century; many examples of this and the fifteenth century are beautifully decorated, being cusped, feathered, paneled, pierced with a series of trefoils, quatrefoils, etc., or carved with foliage. After the medieval period barge-boards gradually become less bold and rich in treatment. Also called gable-board.

Usage


In science:

The Coanda effect is also used by the so-called ‘bargeboards’, aerodynamic appendages typically sited between the trailing edge of the front wheels and the leading edge of the sidepods (see Figure 7).
Explanation and discovery in aerodynamics
Bargeboards are used to guide turbulent air from the front wing wake, away from the vital airflow underneath the car.
Explanation and discovery in aerodynamics
In addition, the lower trailing edge of a bargeboard creates a vortex which travels down the outer lower edge of the sidepod, acting as a surrogate skirt, helping to seal the lower pressure area under the car.
