摘要

为了解决常规粒子图像测速系统(PIV)对小于20%主流速度的弱次流场进行测量时无法得到可靠矢量场的问题

通过调整第二束片光使其沿主流方向偏移1～1.5 mm来跟踪粒子运动

实现了对高速流动中弱二次流瞬态速度场的可靠测量.在此基础上

组合调制4束激光片光的触发时序和空间位置

使不同时间触发的片光能跟踪粒子的运动

再结合2套互相关CCD和偏振光技术

可获得3组高时间分辨率的连续瞬态矢量场

从而实现了对非定常二次流质点运动及涡系结构演绎过程的跟踪测量.

Abstract

It is unreliable or infeasible that normal PIV is used to test the weak secondary flow field whose velocity is less than 20% of the main flow velocity. In this study

a new method was proposed to obtain reliable measuring results for instantaneous vector field of weak secondary flow in high velocity flow. The second light sheet was modulated to the plane of 1.0-1.5 mm downstream from the first light sheet to trace the motion of particles. In order to measure quantitatively the evolvement of particle motion and vortex structure for time-dependent secondary flow

the sequence in time and space of four laser light sheets was modulated so that the motion of the particles in four transient states could be continuously traced by two sets of double-exposure CCD. The results show that three instantaneous vector fields with high time resolution can be obtained.
