Definition - What does Laminar Flow mean?
This phenomenon takes place when a solution flows in a parallel direction without interruption between each layer. At low velocities, fluid seems to flow with no lateral mixing—adjacent layers glide past each other, similar to playing cards. Fluid swirls, eddies and cross currents are nowhere to be found vertical to the flow. This is precisely characterized as a flow system described by short momentum convection and elevated momentum diffusion.
Laminar flow is also referred to as streamline flow.
Corrosionpedia explains Laminar Flow
Determining the kind of flow that is taking place in a solution is essential when it comes to issues in fluid dynamics. The Reynolds number, which is a dimensionless parameter, is capable of defining whether the flow is turbulent or laminar. When the Reynolds number is under the crucial value of about 2040, the motion of the fluid will be completely laminar; at a higher number, the flow can be defined as turbulent. If the number is below 1, stokes or creeping flow occurs, which is an ultra-laminar flow case where the effects of friction are higher compared to the inertial forces.
