Flow control (data)
Flow control, also known as modem flow control, is a data communications mechanism that keeps a sender from overrunning a receiver's buffers, using stop-and-wait or sliding window methods.
Flow control valve
A flow control valve regulates the rate of fluid passing through hydraulic or pneumatic circuits by varying flow resistance, typically via an adjustable orifice, governing actuator speed.
Flow cytometry
Flow cytometry, also known as fluorescence-activated cell sorting, is a laser-based technique that measures light scatter and fluorescence to analyze thousands of single cells per second.
Flow diverter
Flow diverter: braided intracranial stent (Pipeline, Surpass, Silk) placed across an aneurysm neck to divert flow, cause thrombosis, and enable endothelial healing; needs dual antiplatelet therapy.
Flow divider
A flow divider is a hydraulic component that splits one input stream of pressurized fluid into two or more outputs in a fixed ratio to synchronize cylinders.
Flow duration curve
A flow duration curve (FDC) is a cumulative frequency curve showing the percentage of time specified stream discharges were equaled or exceeded, widely used in hydrology since about 1915.
Flow electrochemistry for scale-up of electrosynthesis
Flow electrochemistry for scale-up of electrosynthesis performs electrochemical organic reactions in continuously operated flow cells, allowing gram-scale processes to reach kilogram scale by simply increasing the number of electrolyzing devices.
Flow focusing
Flow focusing is a microfluidic technique in which a fluid injected between converging streams breaks into uniform droplets, bubbles, or particles, used for emulsions, encapsulation, and drug delivery.
Flow forming
Flow forming, also called tube spinning or power spinning, is a metal forming process in which rollers on a rotating mandrel reduce wall thickness while length increases.
Flow House Bangkok 2. 0
Flow House Bangkok (โฟลว์ เฮาส์ แบงค็อก) is an urban beach club in Bangkok, Thailand, built around a FlowRider wave machine where visitors bodyboard and surf.
Flow injection analysis
Flow injection analysis (FIA) is an automated wet-chemical technique in which a sample is injected into a flowing carrier stream and detected as a transient peak.
Flow La Movie
Flow La Movie, born José Ángel Hernández, was a Puerto Rican producer whose label made "Te Boté" a hit; he died in a 2021 plane crash.
Flow limitation in the iliac artery
Flow limitation in the iliac artery (FLIA) is an exertional leg ischemia in endurance athletes, mainly cyclists, caused by endofibrosis, arterial kinking, or compression; diagnosed by provocative ABPI, Doppler, and NIRS testing.
Flow matching
Flow matching is a simulation-free method for training generative models, introduced in 2022 and by 2025 a backbone of leading image, audio, and video generators.
Flow matching action heads for robot policies
A flow matching action head is a neural network component that generates continuous robot actions in vision-language-action models, introduced with Physical Intelligence's π0 in October 2024.
Flow matching for speech synthesis
Flow matching for speech synthesis is a generative TTS method that learns to carry noise to speech in few steps, used at scale by Meta's Voicebox in 2023.
Flow measurement
Flow measurement is the quantification of the rate or quantity at which a liquid or gas moves through a pipe or channel, as volume or mass flow.
Flow net
A flow net is a graphical solution for two-dimensional steady flow through porous media, used in geotechnical engineering to compute seepage, pore pressures, and exit gradients.
Flow network
A flow network is a directed graph in which each edge has a capacity, with a source that generates flow and a sink that absorbs it; the central problem is finding a maximum flow.
Flow of funds
Flow of funds accounts are double-entry statistical systems recording financial transactions and balance-sheet positions among an economy's sectors, published in the United States as the Federal Reserve's quarterly Z.1.
Flow photochemistry
Flow photochemistry is the practice of running light-driven chemical reactions in a continuous flow reactor, where reactants are pumped through narrow, irradiated tubing for uniform illumination.
Flow photochemistry reactors
A flow photochemistry reactor is a continuous-flow device that pumps reaction solutions through narrow, light-transmitting tubing under uniform irradiation, used in organic synthesis and water treatment.
Flow plasticity theory
Flow plasticity theory is the branch of continuum mechanics that describes permanent plastic deformation of solids by a flow rule, together with a yield criterion and a hardening rule.
Flow Rider
The Flow Rider is a stationary wave machine invented by surfer Tom Lochtefeld, first installed in Texas in 1991 and now at more than 280 venues in over 50 countries.
Flow routing
Flow routing is the family of hydrologic methods that determines the timing and magnitude of a flood wave at a downstream point from upstream data.
Flow separation
Flow separation is the detachment of a fluid's boundary layer from a surface under an adverse pressure gradient, sharply increasing drag and causing wing stall.
Flow shop scheduling
Flow shop scheduling is the problem of sequencing jobs that pass through a series of machines in the same order to optimize objectives such as total production time.
Flow State (Keith Urban album)
Flow State (stylized flow state) is Keith Urban's 13th studio album, released June 12, 2026 on MCA Nashville: ten yacht rock covers from 1972-1981 plus the original "We Go Back" with Michael McDonald, produced with Dann Huff at The Sound, Nashville.
Flow synthesis
Flow synthesis is a method of chemical synthesis in which reagents are pumped continuously through tubing or channels instead of being combined in a batch flask.
Flow tracing
Flow tracing is an experimental fluid dynamics technique that measures fluid motion by tracking tracers such as particles, dyes, or bubbles, yielding trajectories and velocity fields.
