Laser Doppler Anemometry For Flow Measurement, William W. Durgin, Lawrence C. Neale

Office of the Provost Scholarship

Laser doppler anemometers are non-invasive, linear, and inherently precise. Calibration, in the usual sense, is not necessary; length and frequency measurements suffice to establish velocity at a spatial point. Measurements were made at points in the cross-sections of two square ducts containing water flow. The points were selected in conformance with a numerical integration scheme to be used for volumetric flow rate determination from the velocity measurements. The experiments were performed in a primary calibration facility at flows up to 1.25 m3/sec using ducts with sides 46 and 92 cm. The anemometer, operating in forward scatter differential mode …
