Laminar flow or streamline flow in pipes (or tubes) occurs when a fluid flows in parallel layers, with no disruption between the layers. At low velocities, the fluid tends to flow without lateral mixing, and adjacent layers slide past one another like playing cards.

What causes laminar and turbulent flow?
When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity and viscosity of the fluid: laminar flow or turbulent flow. Laminar flow occurs at lower velocities, below a threshold at which the flow becomes turbulent.
How does a laminar water flow work?
A flow is considered to exhibit laminar or streamlined behavior when the fluid particles travel in a smooth, parallel path without any intermixing or disruption between the adjacent layers. Laminar flow is mostly observed in viscous or low-velocity fluids.
How does laminar water flow work?
Laminar flow occurs when the fluid flows in infinitesimal parallel layers with no disruption between them. In laminar flows, fluid layers slide in parallel, with no eddies, swirls or currents normal to the flow itself.

What is laminar flow good for?
Laminar airflow is used to separate volumes of air, or prevent airborne contaminants from entering an area. Laminar flow hoods are used to exclude contaminants from sensitive processes in science, electronics and medicine.
What is a laminar flow of liquid?
Laminar flow or streamline flow in pipes (or tubes) occurs when a fluid flows in parallel layers, with no disruption between the layers. At low velocities, the fluid tends to flow without lateral mixing, and adjacent layers slide past one another like playing cards.
Why does flow transition from laminar to turbulent?
The change from laminar to turbulent regime—the so-called laminar-turbulent transition—often originates from an instability phenomenon (Fig. 17). In a two-dimensional flow, the boundary layer is laminar near the leading edge. Downstream, traveling waves occur naturally, and the flow is unsteady.
Understanding Laminar And Turbulent Flow
What causes laminar flow in water?
Laminar flow generally occurs when the fluid is moving slowly or the fluid is very viscous.
What is laminar flow and its uses?
Laminar Airflow Applications The purpose of laminar flow is to provide clean air while displacing contaminants from a zone. It is important that there is little to no entrainment of room air and particulate so that the conditioned zone is kept clean and clear of contamination.
Turbulent Flow Is More Awesome Than Laminar Flow
What are the factors that affecting laminar flow?
Flow patterns in a fluid (gas or liquid) depend on three factors: the characteristics of the fluid, the speed of flow, and the shape of the solid surface. Three characteristics of the fluid are of special importance: viscosity, density, and compressibility.
What is laminar flow in simple terms?
laminar flow, also called streamline flow, type of fluid (gas or liquid) flow in which the fluid travels smoothly or in regular paths, in contrast to turbulent flow, in which the fluid undergoes irregular fluctuations and mixing.
