Question 1.
What is a stream function?
Show hintHide hint
Think about how we combine two velocity components.
Question 2.
Name an application of stream functions in fluid dynamics.
Show hintHide hint
Consider areas where complex flow needs to be simulated.
3Question 3.
What is a stream function?
- A way to measure fluid density
- A mathematical function to describe fluid flow
- A physical representation of fluid motion
Show hintHide hint
Focus on definitions discussed in class.
4Question 4.
The divergence of the velocity field must equal what for steady fluid flows?
- True
- False
Show hintHide hint
Recall the mass conservation equation from our discussions.
Question 5.
Develop a numerical simulation using a stream function to depict the flow around a cylinder. Consider the parameters such as fluid density and velocity.
Show hintHide hint
Start with a basic cylindrical flow and apply the principles we've learned.
Question 6.
Analyze a real-world application where stream functions are used in engineering, such as in the design of aircraft or underwater vehicles. Discuss how they optimize performance.
Show hintHide hint
Research examples of aircraft or submarines that utilize computational fluid dynamics.
