Definition von laminar flow im Englisch Englisch wörterbuch: A smooth, streamline type of viscous flow in which the fluid behaves as a system of orderly layers, with no eddies or irregular fluctuations; The type of fluid flow where all particles of the fluid move in paths parallel to each other and to the direction of flow, without cross motion from one path to another In general, this type of flow occurs only at very low average velocities, or in fluids having a high viscosity index; Fluid flow in which entire layers have the same velocity; Streamlined flow of a fluid where viscous forces are more significant than inertial forces, generally below a Reynolds number of 2000; The type of flow that occurs when viscosity forces predominate and the particles of the fluid move in smooth, parallel paths; Nonturbulent flow of air in layers (flowing in a vertical direction in the case of a biosafety hood); In fluid flow, a smooth flow in which no crossflow of fluid particles occur between adjacent streamlines; hence, a flow conceived as made up of layers - commonly distinguished from turbulent flow; air flow in which essentially the entire body of air within a confined area moves with uniform velocity and direction as the ambient atmosphere being sampled; The linear motion of a fluid; Slow, smooth flow, with each drop of water traveling a smooth path parallel to its neighboring drops Laminar flow is characteristic of low velocities, and particles of sediment in the flow zones are moved by rolling or saltation; A flow in which rapid fluctuations are absent; a flow in which the movement of particles is parallel and straight; Smooth flow with no mixing across stream lines Characterised by low Reynolds number; A flow in which fluid moves smoothly in streamlines in parallel layers or sheets The stream lines remain distinct and the flow directions at every point remain unchanged with time It is characteristic of the movement of ground water Contrasts with turbulent flow Synonymous with Streamline Flow and Viscous Flow; smooth, viscosity dominated flow; Smooth and regular fluid flow -- the direction of motion at any point remaining constant as if the fluid were moving in a series of layers sliding over one another without mixing; Streamlined flow with no turbulence It is a filtration system used through virtually all clean room processing operations to control airflow and velocity at workstations within the fab The "path" the airflow takes is optimized to keep airborne particles from coming in contact with the wafers; A type of flow in which the fluid moves in parallel lines Contrast with turbulent flow; State of fluid flow, where the particles move along parallel, ordered paths Results in low friction on submerged surfaces, but has problems to follow retreating shapes (e g fuselage tails, airfoil behind location of maximum thickness) see also: Turbulent Flow; streamline flow in a viscous fluid near a solid boundary; The movement of a fluid, usually at low velocity and, therefore, at low kinetic energy levels, in which the molecules of the fluid flow along smooth parallel lines called streamlines; Nonturbulent flow of a viscous fluid in layers near a boundary, as that of lubricating oil in bearings. Fluid flow in which the fluid travels smoothly or in regular paths. The velocity, pressure, and other flow properties at each point in the fluid remain constant. Laminar flow over a horizontal surface may be thought of as consisting of thin layers, all parallel to each other, that slide over each other. It is common only where the flow channel is relatively small, the fluid is moving slowly, and its viscosity is relatively high. Examples include the flow of oil through a thin tube and blood flow through capillaries. See also turbulent flow; when the neighboring layers of a moving liquid slide by each other smoothly; nonturbulent streamline flow in parallel layers (laminae); – a type of fluid flow in which the layers move smoothly past each other without crossing paths (see streamline); Movement of water within a stream that occurs as uninterrupted parallel flows Laminar flow generally occurs in areas where friction is low
laminar flow clean room: a clean room free of all extraneous particles; used in fabricating microprocessors
