Can you have an infinite boundary layer

WebThe basic three-dimensional flow is shown to be susceptible to travelling wave disturbances that propagate along the attachment line. The effect of suction on the instability is discussed and the results suggest that the attachment line boundary layer on a swept wing can be significantly stabilized by extremely small amounts of suction.

WebSep 24, 2024 · The boundary layer is the region of a flow close to a surface, where there is a gradient of velocity between zero at the wall and the free-stream velocity ( v ∞ ), which is caused by viscosity and the no-slip condition. It is also possible to have boundary layers for other flow variables, e.g. temperature or scalar concentration.
