Challenge Problems
Push your limits with challenges.
Question 1
Given a stream function, derive the expressions for velocity components u and v and prove if the flow is steady or unsteady.
💡 Hint: Focus on differentiating correctly and applying the definitions of velocity components.
Question 2
Consider a scenario where you have a compressible flow. How would you modify the stream function to account for density variations?
💡 Hint: Reflect on the main differences between compressible and incompressible formulations.
