Fluid dynamic bearing

A fluid dynamic bearing is a non-contact bearing where an oil film levitates the shaft, replacing ball bearings in hard disk drive motors from the mid-1990s.

Fluid dynamics

Fluid dynamics, also called fluid motion, is the branch of fluid mechanics describing how liquids and gases move and the forces that act on them, studied alongside fluid statics.

Fluid in peritoneal cavity (ICD-11 ME04.0), also called peritoneal effusion or ascites when pathological; free abdominal fluid, ~80% from cirrhosis in the US, diagnosed by paracentesis and SAAG ≥1.1 g/dL.

Fluid mechanics

Fluid mechanics, also known as fluid physics or mechanics of fluids, is the branch of mechanics studying liquids and gases at rest and in motion, with applications from aircraft to blood flow.

Fluid mosaic model

Fluid mosaic model: Singer and Nicolson's 1972 model of cell membranes as a fluid phospholipid bilayer with embedded amphipathic proteins; later updated with lipid rafts, cytoskeletal fences, and protein crowding.

Fluid of light

A fluid of light, or quantum fluid of light, is an ensemble of photons that behaves collectively as a quantum fluid, acquiring effective mass and mutual interactions in a nonlinear medium.

Fluid ounce

The fluid ounce (fl oz) is a unit of liquid volume, with a US version of about 29.57 mL and a slightly smaller British imperial one of about 28.41 mL.

Fluid queue

A fluid queue is a stochastic model of a buffer filling and draining fluid at rates set by a background Markov chain, developed for dams in the 1950s.

Fluid shift and orthostatic intolerance in spaceflight

Fluid shift and orthostatic intolerance in spaceflight is the headward movement of body fluid in weightlessness, which reduces blood volume and causes fainting on return to gravity.

Fluid simulation

Fluid simulation is the numerical computation of liquid and gas behavior on a computer, used in engineering CFD and in visual effects for film and games.

Fluid Therapy

Fluid therapy is a medical treatment that restores the volume and composition of body fluids to normal water-electrolyte balance, given intravenously, orally, by gavage, or under the skin.

Fluid-attenuated inversion recovery MRI

Fluid-attenuated inversion recovery (FLAIR) is an MRI pulse sequence that suppresses cerebrospinal fluid signal so lesions near fluid stand out, especially in multiple sclerosis, first reported in 1992.

Fluid–structure interaction

Fluid–structure interaction, or FSI, is the coupled physics in which fluid forces deform a solid and structural motion changes the flow, governing airplane wings, bridges, and blood flow.

Fluidic elastomer actuator

A fluidic elastomer actuator (FEA) is a soft robotic actuator in which pressurized air or liquid inflates chambers molded inside a flexible elastomer, producing bending, twisting, or contraction.

Fluidic oscillator

A fluidic oscillator is a device that converts a steady supply of fluid into a periodic oscillating output with no moving parts, used in flow meters and soft robotics.

Fluidigm

Fluidigm Corporation, renamed Standard BioTools Inc. in April 2022, is a life-science instruments company founded in 1999, known for integrated fluidic circuits, the BioMark PCR system, and mass cytometry.

Fluidization

Fluidization is the process in which an upward fluid flow suspends solid particles so the bed behaves like a boiling liquid, used in fluidized bed combustion and drying.

Fluidized bed combustion

Fluidized bed combustion is a method of burning solid fuel particles suspended in upward-flowing air at 840–950 °C, tolerating low-grade fuels and capturing sulfur with limestone.

Fluidized bed gasifier

A fluidized bed gasifier is a reactor that converts solid fuel, most often biomass, into combustible gas by suspending it in an upward flow of air, steam, or oxygen.

Fluidized bed reactor

A fluidized bed reactor is a vessel in which upward-flowing gas or liquid suspends solid particles so the mixture behaves like a boiling liquid during chemical reaction.

Fluidra

Fluidra is a Spanish multinational maker of swimming pool and wellness equipment, founded in 1969 and headquartered in Sabadell, Barcelona, with brands including AstralPool, Zodiac, and Jandy.

Fluidstack

Fluidstack is an AI data-center company, founded in 2017 as an Oxford University spin-out, that builds and operates computing clusters without owning the chips inside them.

Fluindapyr

Fluindapyr (Onsuva, FMC/Isagro, 2021) is a racemic pyrazolecarboxamide SDHI (FRAC Group 7) fungicide, CAS 1383809-87-7, for cereals, soybeans, corn, and tree nuts; not EU-approved, JMPR 2022 ADI 0-0.04 mg/kg bw.

Fluindione

Fluindione (Previscan), an indanedione vitamin K antagonist oral anticoagulant, ATC B01AA12, marketed only in France; initiation banned since 1 December 2018 over severe immuno-allergic risk, use limited to renewals.

FLUKA

FLUKA, or FLUKA Particle Transport Code, is a general purpose Monte Carlo code simulating hadrons, leptons, and photons from keV to cosmic ray energies, developed at CERN and INFN.

Fluke (band)

Fluke: English electronic band formed 1988 by Jon Fugler, Mike Tournier, and Mike Bryant; progressive house to big beat; known for 'Atom Bomb', Risotto, Puppy, and 2026's The Second Bite.

Fluke (film)

Fluke is a 1995 American fantasy drama directed by Carlo Carlei, adapted from James Herbert's 1977 novel, in which a workaholic killed in a car crash is reincarnated as a dog.

Flula Borg

Flula Borg (born 1982, Erlangen) is a German actor, comedian, DJ, and YouTuber known for Pitch Perfect 2's Pieter Krämer, Javelin in The Suicide Squad, Skip Tracer Randy in The Rookie, and Comfortable Doug in Centaurworld.
