boundary layer

• Тонкий слой жидкости (например, воздуха или воды), который образуется непосредственно у твёрдой поверхности, где вязкость и трение существенно влияют на поток; обычно изучается в физике, аэродинамике и инженерии.

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.
