Question 1
A flat plate experiences a laminar flow at a Reynolds number of 4.5 x 10^4. Compute the displacement thickness at a location where the distance from the leading edge is 0.5m.
💡 Hint: Use the equation for displacement thickness related to Reynolds number.
Question 2
Discuss how the development of Computational Fluid Dynamics (CFD) has impacted the analysis of boundary layers compared to classical methods.
💡 Hint: Consider the evolution from manual calculations to automated simulations.
