Challenge Problems
Push your limits with advanced challenges
A fluid particle moves through a region where the velocity field changes. Given the velocity function V = (x^2 + y^2)i + (3xy)j, calculate the local and convective acceleration at the point (1, 2).
💡 Hint: Use the derivatives of the components of the velocity function and apply the necessary transformations.
In a steady-flow scenario where the velocity field is represented as V = (4x - y)i + (10 - z)j, establish the conditions for local and convective terms, and demonstrate their calculation.
💡 Hint: Look carefully at how the rate of change is influenced by fixed versus moving boundaries.
