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
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

Doppler-Anemometer — Animation eines Schalensternanemometers Geräte zur Messung der Windgeschwindigkeit werden gemeinhin als Anemometer (von griechisch anemos (ἄνεμος) = Wind) oder Windmesser bezeichnet. Allerdings hat sich der Begriff Anemometer inzwischen auch als… … Deutsch 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
Laser-Doppler-Anemometrie — 2D Laser Doppler Anemometer an einem Strömungskanal. Zwei Strahlpaare leicht unterschiedlicher Wellenlänge dienen der Messung der Längs bzw. vertikalen Komponente der Strömungsgeschwindigkeit am Ort des Schnittpunkts. Das Objektiv ist mit dem… … Deutsch Wikipedia
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
