Laminar flow...#physics

追加: 2026-06-03

Laminar flow is an orderly fluid dynamic regime where a liquid or gas moves in smooth, parallel layers (laminae) with minimal to no mixing between them, occurring in slow-moving fluids with high viscosity inside small or smooth flow channels; it is characterized by predictable particle paths, no cross-currents or eddies, and is governed by the Reynolds number (typically below 2000 for pipes), where viscous forces dominate inertial forces, resulting in reduced energy loss compared to turbulent flow.
