2 cards from this section. Quick, good the night before a test.
Define a stream function. What is its purpose?
Think about how it relates to velocity.
What does CFD stand for?
It involves computing fluid flows.
What is the primary benefit of using stream functions?
Think about the stream function's purpose.
True or False: Streamlines can cross one another in a fluid flow.
What happens if multiple streamlines intersect?
A stream function is given by Ψ(x,y) = x^2 + y^2. Determine the velocity components u and v at the point (1,1).
Use partial derivatives to find u and v.
Describe how the flow around a wing of an aircraft can be modeled using stream functions. What assumptions would need to be made?
Think about the nature of airflow and the Bernoulli principle.
