Challenge Problems
Push your limits with advanced challenges
A flat plate in a fluid flow is experiencing boundary layer formation. Given initial velocity profiles, compute both momentum thickness and displacement thickness at several points along the plate.
💡 Hint: You may need to derive the equations based on given profiles.
Analyze how changes in fluid viscosity can impact the momentum thickness behavior on different surfaces—smooth vs. rough.
💡 Hint: Think about how viscous fluids flow differently compared to non-viscous ones.
