Eulerian and Lagragian views

  1. Mar 31, 2017 #1
    Is Eulerian view valid when the flow is unsteady? I think Eulerian view is valid only for steady flows because the points in the flow domain should be with constant velocities.

    Thank you.

    Neither the Eulerian nor Lagrangian descriptions of a flow field care whether the flow is steady or not. Both are valid for unsteady flows.
