| 摘 要： | 以标准桨DTMB-P4119为试验对象,开展了螺旋桨尾流场测试分析。试验捕捉到了清晰的螺旋桨梢涡和尾涡的流动结构以及梢涡、尾涡片在尾流中的演化。分析比较了三种载况下的尾流特征,利用捕捉到的梢涡涡心坐标计算了部分涡线的螺距角。文章将测试结果与LDV测试数据进行了比较分析,结果表明,PIV与LDV对微观流动结构的测量取得了比较一致的结果。

| Abstract: | The 2D-PIV(Particle Image Velocimetey) technique is applied to measure the flow characteristics of complex flow around the DTMB-P4118 propeller.The test captures the spatial evolution of the propeller wake,including tip vortex and trailing vortex sheet.Also,this paper compares the wake's characteristic of three different work conditions,and calculated the angle of pitch of some of tip vortex line using the coordinate figure which captured in the test.And the comparison experiment was carried out to measure ... |
