Turbulent flow is a less orderly flow regime that is characterized by eddies or small packets of fluid particles, which result in lateral mixing. The threshold velocity is determined by a dimensionless parameter characterizing the flow called the Reynolds number, which also depends on the viscosity and density of the fluid and dimensions of the channel. Laminar flow occurs at lower velocities, below a threshold at which the flow becomes turbulent. 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 is a flow regime characterized by high momentum diffusion and low momentum convection. ![]() In laminar flow, the motion of the particles of the fluid is very orderly with particles close to a solid surface moving in straight lines parallel to that surface. There are no cross-currents perpendicular to the direction of flow, nor eddies or swirls of fluids. At low velocities, the fluid tends to flow without lateral mixing, and adjacent layers slide past one another like playing cards. In fluid dynamics, laminar flow is characterized by fluid particles following smooth paths in layers, with each layer moving smoothly past the adjacent layers with little or no mixing. This flow profile of a fluid in a pipe shows that the fluid acts in layers that slide over one another. ![]() Connections for BAS standard.The velocity profile associated with laminar flow resembles a deck of cards.
