Challenge Problems
Push your limits with challenges.
Question 1
Determine the momentum thickness for an incompressible flat plate flow given a parabolic velocity profile and conditions around it.
💡 Hint: Set up the integral formula properly considering the limits from zero to the boundary layer thickness.
Question 2
Analyze how displacement thickness would change if the free stream velocity increased significantly and discuss the implications.
💡 Hint: Consider the relationship between velocity and effects on the flow structure.
