Who introduced the concept of the theory of boundary layer?
A boundary layer
Select the wrong statement pertaining to flow beyond the outer edge of boundary layer:
In a boundary layer developed along the flow, the pressure decreases along the downstream direction. The boundary layer thickness would
The laminar sublayer is
In a hydrodynamically smooth surface the roughness magnitude ∈ and laminar sublayer thickness δ' are related as
The thickness of laminar sublayer δ' is given by
The laminar sublayer is usually very thin and it! thickness δ' is found hv exneriments to be
The separation of boundary layer takes place when the pressure gradient is
In advance pressure gradient boundary layer flow the boundary layer may at some section leave the boundary. This is called as separation and downstream of the separation section turbulent eddies exist and this disturbed region is called as wake.
The boundary layer separates from the surface when
dp/dx ≠ 0
Some times and under conditions, the boundary layer will leave the surface and curl up into a vortex or whirl pool. This phenomenon is known as
