摘　　要：采用PIV瞬态流场测试技术,利用环形喷管,对水槽内法向面上一个截面上的速度矢量场和涡量场进行测量。定量分析不同雷诺数对速度场和涡量场的影响,描述水槽内涡旋的形成及其影响因子。分析涡旋流场强化传质的本质。结果表明,通过改变流量引起雷诺数的变化,改变了水槽内涡流的特性。为研究油品调和的流场提供一种途径。A technology for direct experimental measurement of velocity vectors and vorticity field in one section of normal plane, using annularity spray nozzle, formed in flume with the time-reserved particle image velocimetry （PIV） is presented. The influence of different Reynolds number on flow field and vorticity field is analyzed quantificationally. The formation of vortex in flume, and the influence factors are described. The inner character of mass transfer is analyzed by vortex field.It is discovered that arousing Reynolds number by changing flow change the character of vortex in flume. One kind of approach is provided for analyzing the flow field of oil harmonic.
