Abstract：Principle of the Laser Doppler Velocimetry (LDV) and Adaptive Phase Doppler Velocimetry(APV) system was summarized and the flow field of water mist produced by dust reduction nozzle was measured. Experiment results show that the particle size of water mist is reduced, the range along radial direction, total volume flux of water mist and air in the jet flow is increased as work pressure of the nozzle increased. In the main body of the jet flow, the attenuation of axial velocity both in axial and radial direction is gentle, the radial and tangential velocity have single peak distribu-tion in radial direction, and the efficiency of dust reduction is improved by swirling water jet.
