fluid flow
movement of fluid matter
two-phase flow
simultaneous flow of materials with two thermodynamic phases
hydrothermal circulation
circulation of hot water driven by heat exchange and accompanied by water-rock interactions and alterations
turbidity current
underwater current of usually rapidly moving, sediment-laden water moving down a slope
incompressible flow
fluid flow in which density remains constant
blood flow
continuous circulation of blood
air current
type of concentrated air flow within Earth's atmosphere
flooding
fluid flow phenomenon in a nuclear reactor core
eddy pumping
ocean dynamics
thermionic emission
thermally induced flow of charge carriers from a surface
Knudsen flow
transition between continuous and free molecular flow
supercritical flow
a flow whose velocity is larger than the wave velocity
washing machine
downward current
return flow
water that escapes after irrigation
tidal current
oscillating currents produced by tides
open-channel flow
branch of hydraulics and fluid mechanics
fluid flow through porous media
Manner in which fluids behave when flowing through a porous medium
tide
rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth
circulation
atmospheric flow
free molecular flow
gas flow with a large mean free molecular path
secondary flow
relatively minor flow superimposed on the primary flowby inviscid assumptions
pipe flow
type of liquid flow within a closed conduit
compressible flow
branch of fluid mechanics
current
magnitude and direction of flow in a fluid
rip tide
strong, offshore current that is caused by the tide pulling water through an inlet along a barrier beach, at a lagoon or inland marina where tide water flows steadily out to sea during ebb tide
laminar flow
flow where fluid particles follow smooth paths in layers
plug flow
simple velocity profile model of fluid flow in a pipe, assuming constant velocity and no boundary layer
draught
movement of air through a closed space, that is believed to cause illnesses
suction
flow of a fluid into a partial vacuum, or region of low pressure
slide
mass movement of rock, soil, mud, or snow under the force of gravity
Virgo-centric flow
preferred movement of Local Group galaxies towards the Virgo cluster caused by its overwhelming gravity, which separates bound objects from the Hubble flow of cosmic expansion
density current
a current that arises when multiple densities exist in a liquid
vortex
fluid flow revolving around an axis of rotation
potential flow
velocity field as the gradient of a scalar function
shear flow
Flow induced by force in a fluid
inflow
in meteorology, the flow of a fluid into a large collection of that fluid
Burgers vortex
solution to the Navier–Stokes equations
pouring
flow of a substance from a container, or the action causing such a flow
ion wind
airflow induced by electrostatic forces
leak
process of matter, often liquid, escaping containment
