2 cards from this section. Quick, good the night before a test.
What does the no-slip boundary condition imply?
Think about what happens at the edge of a surface.
Define a boundary layer.
Consider the thickness of fluid layers.
What is the no-slip condition?
Consider what happens at solid surfaces.
True or False: The boundary layer only exists in turbulent flow.
Recall the flow types discussed.
Consider a fluid with a kinematic viscosity of 0.002 m²/s flowing over a plate with a free stream velocity of 3 m/s. If the boundary layer transitions to turbulent flow, at what downstream distance from the leading edge does this transition occur?
Remember to isolate x in your equation.
How would the flow patterns differ if the same fluid had a much higher viscosity? Discuss the implications on the boundary layer.
Think about the relationship of viscosity to flow stability.
