Laser Doppler anemometry Figure 2. A schematic diagram of a HF-pulsed two-dimensional laser Doppler anemometer with a single laser diode and coherent sampling (from [27]). displaced fringes appearing alternately in the measurement volume [28]. Using quadrature de-modulation [291, the flow velocity direction can be measured if the two

Laser-Doppler anemometer investigations are described in boundary-layer flows along bean leaves and a metal model of plant leaves. These measurements formed the basis of heat and mass transfer predictions near leaves for a specific leaf position relative to the free stream and with different turbulence properties imposed onto the oncoming flow.

It is a well-establishedtech-nique that gives information about flow velocity. Its non-intrusive nature and directional sensitivity make it very suitable for appli- The aerodynamics of a laboratory model of an improved four-vortex coal combustion furnace is studied using laser Doppler anemometry. For the isothermal case, the distributions of the averaged velocity and velocity pulsations are obtained for various flow regimes. The main features of the flow are established. The experimental results are compared with previous particle image Laser Doppler Anemometry (LDA) is a technology used to measure velocities of flows, or more specifically the velocity of small particles in flows.

Il laser Doppler legge quindi la "perfusione" dei tessuti, secondo la formula semplificata: Perfusione = Vel X CMBC (Concentration of Moving Blood Cells: Concentrazione delle cellule ematiche in movimento).

Laser Doppler Anemometry (LDA) was used for the simultaneous measurement of the gas and particle velocities in a gas‐solid, two‐phase flow. The flow configuration consists of an air jet at ambient temperature in which a spherical glass powder of a mean particle diameter of 97.0 or 13.7 μm was injected from one side using a secondary air jet. Both principal and secondary jets were also

Laser Doppler anemometer Doppler Effect is a method for measuring linear velocity. When a narrow laser beam ( or radio beam or ultrasonic beam) is focused on an abject, the beam will be reflected back to the source.
