Definition
Laminar flow is a type of fluid flow where the fluid moves in smooth, parallel layers, with no disruption between the layers. Think of it like a deck of cards sliding smoothly, one on top of the other. There's little or no mixing between adjacent layers of the fluid. It's the opposite of turbulent flow, which is chaotic and irregular. Laminar flow occurs at low speeds and with high-viscosity fluids. It's predictable and efficient.
