摘要：

In this work we present a prototype of laser Doppler anemometer (LDA) with direct spectral analysis for investigating dense gas-liquid jets. Such parameters of the prototype as the inaccuracy of measurement, spatial and temporal resolution of the system are determined. It is shown that LDA can be used for the investigation of gas flows with the seeding by smoke particles, the results were verified by PIV technique. For determining the influence of droplets with different velocities in the jet on the LDA results the prototype is tested on the two-velocity jet and the possibility of velocity profile changing due to the redistribution of intensity of light scattered in different regions of the jet is shown.
