Paper Abstract

The integral laser Doppler anemometry (IDA) is considered. In IDA a thin and extended measuring volume is formed across the flow, and Doppler shifts from all particles in this volume are registered simultaneously, giving an integral Doppler spectrum. The theory of IDA is presented for the differential optical arrangement of LDA. It is shown, that under certain conditions easily met in the measurements, the solution of the inverse problem is possible, namely, the reconstruction of the flow velocity profile, or the particles concentration profile from the shape of the measured integral Doppler spectrum. The transverse concentrational profiles of particles in dilute suspension flow in a flat channel of 110 (mu) width are measured using IDA technique.
