WebOct 29, 2024 · In the Lagrangian perspective, f is a function of the particle label a (which is fixed for a given fluid particle, for e.g. its coordinates at some reference time) and time t. In this case, D f / D t = ∂ f / ∂ t. In the Eulerian perspective, f is a function of laboratory coordinates x and time t.
