I am doing research on backward-facing step microchannel. My scope include fully developed flow, however, I can't find definition on the internet nor understand the meaning of it. Can anyone explain full developed flow? Thanks in advanced.

you can interpret fully-developed flows as steady (no-more time-derivative) condition for laminar flows or as statistically energy-steady for laminar unsteady and turbulent flows.

A fully developed flow is when your boundary layer is fully developed, forming a D-shaped velocity profile with 0 velocity at the wall and streamline velocity at the centreline.
