2 cards from this section. Quick, good the night before a test.
What is the Prandtl assumption?
Think about the velocity changes in turbulent flows.
What is a boundary layer?
Consider the influence of surfaces on fluid flow.
What does the Prandtl assumption describe?
Think about the context of turbulent flow and velocity profiles.
True or False: The drag coefficient is independent of the shape of the object.
Recall how different shapes in fluid dynamics could affect drag.
Consider a flow over a flat plate. If the velocity profile deviates from Prandtl's one-seventh power law, discuss how this might impact the shear stress and drag coefficient.
Consider the implications of shear stress adjustments in various engineering applications.
Derive an expression for the turbulent boundary layer thickness as you adjust flow conditions (increasing U or varying fluid viscosity).
Utilize principles of fluid mechanics to relate velocity, viscosity, and boundary layer growth.
