Velocity Field & the Material Derivative
Inside this lesson
- Define the material derivative DV/Dt and identify its local and convective parts
- Compute the acceleration field of a given 2D velocity field
- Explain why a steady flow can still accelerate a fluid particle (the nozzle example)
- Apply the material derivative to a scalar field such as temperature
