摘要
为了研究烟火药火焰结构,尤其是具有较大几何尺寸的高温燃烧质点的运动状态,利用二维粒子成像速度场仪(PIV)对该燃烧过程进行了测量,实现了火焰内部燃烧粒子运动的可视化;针对示踪粒子、滤光片及曝光时间等测试问题进行了研究与分析,并利用MATLAB软件对实验图像进行了验证与研究,获得了可信的实验数据与理论依据。
Particle image velocimetry （PIV） was used to measure pyrotechnical burning process in order to study flame structure, especially high temperature burning particle movement state, and realize visualization of burning particle movement inside flame. In this paper, some problems such as tracer particle, filter and exposure time were studied and analyzed. And credible experiment data and theory foundation were achieved by testing and discussing experiment image based on MATLAB software.
