METHOD FOR MEASUREMENT OF TOTAL VELOCITY VECTOR IN HYDRAULIC FLOWS BY LASER DOPPLER ANEMOMETRY (LDA) Russian patent published in 2017 - IPC G01P3/36 

FIELD: physics, measurement equipment.

SUBSTANCE: invention refers to test and measurement equipment, allows to explore kinematic characteristics of hydraulic flows. The inventive method for measurment of the total velocity vector in a hydraulic flow usinf laser Doppler anemometer (hereinafter - LDA) includes placement of LDA and immersion optical container relative to each other, so that the optical axis of LDA instrument is located at an angle of 90 degrees to the front wall of the immersion optical container, according to the invention several LDA instruments are used emitting a total of 6 laser beams with the same wavelengths. At that, an optical immersion container is used with a front wall having the number of faces equal to the number of LDA instruments.

EFFECT: invention provides the possibility of simultaneous measurement of three components of the velocity vector (total velocity vector) at the same point of the hydraulic flow.
