3 cards from this section. Quick, good the night before a test.
What is the formula for calculating wall shear stress in turbulent flow?
Focus on how shear stress is related to velocity and boundary layer thickness.
Describe what a boundary layer is.
Think about the interaction of fluid and surfaces.
What does the von Karman momentum integral method analyze?
Remember its application in turbulent and laminar analyses.
True or False: The boundary layer thickness for a turbulent flow can be represented as proportional to x^0.8.
Think back to the differences we discussed in class.
A fluid with a viscosity of 0.001 Pa.s, density of 1000 kg/m³ and a speed of 2 m/s flows over a flat plate. Calculate the boundary layer thickness at a distance of 5 m if it is turbulent.
Remember to relate the Reynolds number and your flow conditions.
For a given turbulent flow, derive the relation for drag coefficient as a function of Reynolds number.
Refer to previous lessons on how C_D behaves in different flow regimes.
