Velocimetry — is the measurement of the velocity of fluids, as often used to solve fluid dynamics problems, or to study fluid networks, as well as in industrial and process control applications, or in the creation of new kinds of fluid flow sensors. Methods of … Wikipedia
velocimetry — ve·lo·cim·e·try (ve″lo simґə tre) measurement of speed, such as speed of flow. See also flowmeter … Medical dictionary

Particle image velocimetry — (PIV) is an optical method used to measure velocities and related properties in fluids. The fluid is seeded with particles which, for the purposes of PIV, are generally assumed to faithfully follow the flow dynamics. It is the motion of these… … Wikipedia
Molecular tagging velocimetry — (MTV) is a specific form of flow velocimetry, a technique for determining the velocity of currents in fluids such as air and water. In its simplest form, a single write laser beam is shot once through the sample space. Along its path an optically … Wikipedia
Particle tracking velocimetry — (PTV) is one of velocimetry methods, i.e a technique to measure velocity of particles. The name suggests that the particles are tracked, and not only recorded as an image as it is suggested in another form, particle image velocimetry. There are… … Wikipedia
Planar Doppler velocimetry — (PDV), also referred to as Doppler Global Velocimetry (DGV), determines flow velocity across a plane by measuring the Doppler shift in frequency of light scattered by particles contained in the flow. The Doppler shift, Δfd, is related to the… … Wikipedia
Laser Doppler velocimetry — (LDV, also known as laser Doppler anemometry, or LDA) is a technique for measuring the direction and speed of fluids (or any other material that is processed like metal, paper etc) like air and water. In its simplest form, LDV crosses two beams… … Wikipedia
Hydroxyl tagging velocimetry — (HTV) is a velocimetry method used in humid air flows. Themethod is often used in high speed combusting flows because the high velocity and temperatureaccentuate its advantages over similar methods. HTV uses a laser (often an argon fluoride… … Wikipedia
