Description
Summary:The present study is aimed at the development of a laser Doppler anemometer (LDA) for investigating high-velocity multiphase flows. Based on the analysis of the Doppler anemometry methods, requirements to modern LDAs for solving the above-mentioned problems are formulated, and the ways of their implementation with allowance for the present status of laser engineering and spectroscopy are outlined. A prototype of the anemometer with direct spectral analysis with the most updated elemental base is presented. Its workability is demonstrated by an example of supersonic gas-liquid jets; it is also shown that the anemometer can also be applied to solve other problems.
