Vd. Pogrebennik, INVESTIGATION OF SYSTEMATIC-ERRORS IN MEASUREMENTS OF THE ROTATIONAL COMPONENT OF A FLOW VELOCITY, Measurement techniques, 40(9), 1997, pp. 904-911
An investigation is made of the systematic errors in measurements of t
he rotational component of a flow velocity. Recommendations are made o
n the choice of the size of the measurement contour relative to the ra
dius of the vortex.
