Challenge Problems
Push your limits with advanced challenges
For a flat plate, given the velocity profile u/U = y^3/delta^3, derive the displacement thickness, momentum thickness, and energy thickness.
💡 Hint: Use integrals for each to find thickness values using given velocity profiles.
Discuss the effects of a turbulent boundary layer on the three thicknesses compared to a laminar boundary layer.
💡 Hint: Contrast between flow nature in laminar versus turbulent conditions.
