Test: Boundary Layer Theory - 2 - Question 1

The separation of boundary layer can be reduced by

Test: Boundary Layer Theory - 2 - Question 2

It is recommended that the diffuser angle should be kept less than 18° because

Detailed Solution for Test: Boundary Layer Theory - 2 - Question 2

If diffuser angle is more, eddies formation may takes place and also flow separation may occurs.

Test: Boundary Layer Theory - 2 - Question 3

Boundary layer separation is caused by

Detailed Solution for Test: Boundary Layer Theory - 2 - Question 3

Boundary layer separation is caused due to adverse pressure gradient or positive pressure gradient.

Test: Boundary Layer Theory - 2 - Question 4

Laminar sub-layer acts as

Detailed Solution for Test: Boundary Layer Theory - 2 - Question 4

In turbulent flow analysis along the boundary layer, a thin layer of fluid in the immediate neighbourhood of the boundary where viscous shear stress is predominant while the shear stress due to turbulence is negligible. This portion is known as laminar sublayer.
In turbulent flow heat transfer is more as compared to laminar flow and also is this laminar sublayer heat transfer is very less while, it is present is turbulent flow hence it acts as insulating medium in turbulent flow.

Test: Boundary Layer Theory - 2 - Question 5

At the point of boundary layer separation

Detailed Solution for Test: Boundary Layer Theory - 2 - Question 5

Test: Boundary Layer Theory - 2 - Question 6

If u = free stream velocity
u = local velocity.
δ = boundary layer thickness
Then the momentum thickness θ is given by

Test: Boundary Layer Theory - 2 - Question 7

The energy thickness δe is given by

Test: Boundary Layer Theory - 2 - Question 8

The displacement thickness δ* is

Test: Boundary Layer Theory - 2 - Question 9

Given that
δ = boundary layer thickness
δ* = displacement thicknes
δe = energy thickness
θ = momentum thickness
The shape factor H is given by

Detailed Solution for Test: Boundary Layer Theory - 2 - Question 9

Shape factor is given by

Test: Boundary Layer Theory - 2 - Question 10

Boundary layer flow separates from the surface if

Detailed Solution for Test: Boundary Layer Theory - 2 - Question 10

Boundary layer separation occurs at adverse pressure gradient
