| Abstract: | The APV(Adaptive Phase/Doppler Velocimetry)system can be used to measure the particle size and velocity adaptively according to the Doppler frequency shift and the Doppler phase shift theory.Through the light scattering theory of inconductive spherical particles,the layout of the APV system was studied,and measure flow field of the entraimment water mist. |

| Keywords: | phase Doppler measurement of the flow field of the entraimment water mist |
