Question 1

What is a velocity potential function?

  • A scalar function whose gradient represents flow velocity
  • A vector function that describes rotational flow
  • A mathematical concept unrelated to fluid dynamics

💡 Hint: Think about the relationship between scalar and vector fields.

Question 2

True or False: Irrotational flow allows for the application of velocity potential functions.

  • True
  • False

💡 Hint: Recall the definition of irrotational flow.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a fluid flowing past a flat plate with known boundary conditions. Derive the velocity potential function given that the flow is irrotational.

💡 Hint: Remember to apply the proper mathematical transformations for irrotational flows.

Question 2

In a turbulent flow scenario, discuss why velocity potential functions cannot be applied and provide alternative approaches to analyzing such flows.

💡 Hint: Focus on the concept of vorticity and how it affects fluid characteristics.
