2 cards from this section. Quick, good the night before a test.
What does the mass conservation equation for boundary layers express?
Think about how mass flows in different directions.
Define displacement thickness.
Consider how mass flow changes at the boundary.
What is the primary purpose of the boundary layer equations?
Think about applications where drag is important.
True or False: Displacement thickness increases velocity in the boundary layer.
Consider how viscosity impacts flow near surfaces.
Calculate the drag force on a plate if the boundary layer thickness is known to be 1mm, with a momentum thickness of 0.01mm. Use appropriate fluid properties and flow characteristics.
Involves integrating the given thicknesses into momentum equations.
Discuss how modern computational methods have changed the analysis of boundary layers compared to historical methods used by Prandtl.
Focus on how technology enables us to solve previously unsolvable equations.
