边界层

边界层示意图,图中可看出由层流演变为紊流的过程

边界层,又称附面层是一个流体力学名词,表示流体中紧接着管壁或其他固定表面的部份。边界层是由黏滞力产生的效应,和雷诺数Re有关。

一般提到的边界层是指速度的边界层。在边界层外,流体的速度接近定值,不随位置而变化。在边界层内,在固定表面上流速为0,距固定表面越远,速度会趋近一定值。

Boundary layer 边界层

Boundary layer visualization, showing transition from laminar to turbulent condition
Ludwig Prandtl
Laminar boundary layer velocity profile
Velocity Boundary Layer (Top,orange) and Temperature Boundary Layer (Bottom, green) share a functional form due to similarity in the Momentum/Energy Balances and boundary conditions.

In physics and fluid mechanics, a boundary layer is the layer of fluid in the immediate vicinity of a bounding surface where the effects of viscosity are significant. In the Earth's atmosphere, the atmospheric boundary layer is the air layer near the ground affected by diurnal heat, moisture or momentum transfer to or from the surface. On an aircraft wing the boundary layer is the part of the flow close to the wing, where viscous forces distort the surrounding non-viscous flow. See Reynolds number.
