  • frCouche mince de fluide (par exemple, air ou eau) qui se forme directement contre une surface solide, où la viscosité et le frottement influencent fortement l'écoulement ; étudiée principalement en physique, aérodynamique et ingénierie.

A thin layer of fluid (such as air or water) that forms immediately adjacent to a solid surface, where viscosity and friction significantly affect the flow, commonly studied in physics, aerodynamics, and engineering.

  1. Fluid dynamics layerC2formal

    The thin layer of fluid (liquid or gas) that forms immediately adjacent to a solid surface, where viscous forces are significant and the flow velocity changes from zero at the surface to the free-stream velocity.

    • Engineers study the boundary layer to reduce drag on aircraft wings.
    • The boundary layer can transition from laminar to turbulent flow.
    • Heat transfer is strongly influenced by the properties of the boundary layer.
