Challenge Problems
Push your limits with challenges.
Question 1
Analyze a two-dimensional incompressible flow field defined by the stream function ψ = x²y - y³. Derive the velocity components and verify the continuity equation.
💡 Hint: Use partial differentiation and remember continuity principles.
Question 2
Evaluate the flow around a rotating cylinder modeled by the stream function ψ = r²θ. Can you describe the behavior of the flow and identify any critical points?
💡 Hint: Visualize fluid paths around a moving object.
