Analysis of the accuracy of the third component of flow velocity measurements for 3-component, 3-color laser Doppler anemometer

摘要

The special survey of dependency of the measurement of the third component of flow velocity (axial component) of angle between both channels of the LDA system is presented. The influence of the angle between me flow velocity vector and the laseranemometer optical axis upon the accuracy of the obtained results is also analyzed.Systematic errors which are the results of a component choice and transmitting - receiving opto-electrical subsystem arrangement are discussed, too
