4 cards from this section. Quick, good the night before a test.
What is a boundary layer?
Think about how fluid behaves when it touches a solid.
Define laminar flow.
Consider a steady stream of smooth water.
What defines a boundary layer?
Think about where the viscous effects are significant.
Reynolds number helps determine whether the flow is laminar or turbulent.
Recall what the critical values indicate.
Given a flat plate with a flow Reynolds number of 1×10^6, discuss the implications for boundary layer thickness and transitions in flow behavior.
Refer to the relationship between Reynolds number and flow behavior.
Explore the impact of boundary layer thickness on drag force for an aircraft wing design. How would you go about modifying a design to reduce drag?
Consider how shape and surface treatments affect flow types.
