15 صفحه اولTissue blood flow measurement by laser Doppler technique
Measurement of blood flow and the effects of different factors on tissue blood flow are important fields of research in physiology and pharmacology. So far, different methods have been innovated, using laser light is the Last one. In this article history, principles and specifications of laser technique along with its advantages and disadvantages ( in comparison with other methods) are revie...
متن کاملMeasurement of Reynolds Stress Distribution in a Fluidic Element by the Laser Doppler Velocimeter
The one-phase flow and the two-phase flow in a fluidic element are investigated by measuring Reynolds stress distributions of the main jets using the laser Doppler velocimeter. In the one-phase flow, a water flow jets from a main nozzle into water and in the two-phase flow, a water fiow jets into air. Some results with the one-phase flow are as follows. When either of the two control ports is c...
متن کاملCalibration of the CERTIFIER Air Velocity Calibrator Using a Laser Doppler Velocimeter (LDV)
Introduction Traditionally a Pitot-static tube connected to a pressure transducer is used to make air velocity measurement. Lately, velocity transducers based on the principle of convective heat transfer have become popular. Both types of transducers need occasional calibrations. Also, several regulatory agencies require that the calibration of velocity transducers used in certain applications ...
متن کاملA Sub-Miniature Laser-Doppler Velocimeter for High Speed Flow Measurements
A new laser-Doppler velocimeter (LDV) for high speed flow measurements (three-dimensional flows with speeds greater than 610 m/s) is being developed based in-part upon an existing low speed instrument capable of high resolution, near surface velocity vector measurements. The key technology for the instrument is a sub-miniature laser-Doppler velocimeter (SMLDV); a similar low-speed version of wh...
