Abstract

Theoretical analysis and experimental results are given for a Doppler method that facilitates the assessment of flow parameters, using a sound beam whose axis is perpendicular to the flow. The simplistic Doppler effect formula predicts zero frequency shifts for this geometry. However, the present configuration of a finite aperture and focused beam contains oblique rays which provide the detectable Doppler signals, in spite of the fact that the flow is transverse with respect to the axis. Using pulsed ultrasonic Doppler, with a transducer having a circular aperture, in-vitro flow measurements have been peformed, which compare well with results of classical techniques and are also in agreement with the present theoretical analysis.
