Challenge Problems
Push your limits with challenges.
Question 1
Given a profile where u/U = 0.1 + 0.9 * (y/δ)^2, derive the formula for displacement thickness.
💡 Hint: Break down the integral to manage the two terms separately.
Question 2
For a scenario where the fluid's viscosity is doubled, predict how this impacts the boundary layer thickness.
💡 Hint: Think about how viscous fluids behave compared to less viscous ones.
