Challenge Problems
Push your limits with advanced challenges
Calculate the displacement thickness for a given laminar flow situation with known velocity distributions. If u = 0.6U at y = 0.005m, and U is the free stream velocity, what would B4* be?
💡 Hint: Focus on integrating within the range defined by your boundaries.
Given velocity profiles for a turbulent flow, derive the momentum thickness and discuss its implications on drag force design.
💡 Hint: Incorporate experimental or empirical data for accuracy.
