Challenge Problems
Push your limits with challenges.
Question 1
Given a flow with velocity components u = 2xy, v = -x^2, determine the location of irrotational flow.
💡 Hint: Recall that vorticity is defined as the curl of the velocity field.
Question 2
In an engineered system, a turbine encounters a boundary layer that increases drag by 15%. Discuss possible methods to reduce this effect.
💡 Hint: Think about shapes and surfaces that disrupt flow optimally.
