Boundary Layer Separation and Displacement Thickness
Boundary layer separation occurs when the flow over a surface becomes turbulent and separates from the surface, creating a region of recirculating flow. This separation can have significant effects on the behavior and characteristics of the flow.
Definition of Displacement Thickness
Displacement thickness is a parameter used to quantify the effect of the boundary layer on the overall flow. It represents the thickness of an imaginary layer that, if added to the boundary layer, would result in the same mass flow rate as the actual boundary layer.
Explanation of the Answer
The correct answer to the question is option 'A', which states that displacement thickness increases with boundary layer separation. Here's an explanation of why this is the case:
1. Boundary Layer Separation
- Boundary layer separation occurs when the flow over a surface becomes unstable and detaches from the surface, creating a region of recirculating flow.
- This separation is typically caused by adverse pressure gradients, flow separation due to flow separation due to surface curvature, or flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to flow separation due to
