摘要
使用YAG脉冲激光烧蚀固态POM聚合物和掺碳质量分数为5%的液态甘油混合物,形成羽流场.分别在相机镜头前添加滤光片以及在纹影系统中设置不同的刀口,观察对羽流场像的影响.实验结果表明:滤光片和暗场纹影均能够提高羽流纹影图像的显示效果.
The plume flow field was made using YAG pulse laser ablation of solid POM polymer and carbon doped glycerin liquid mixture （5% mass fraction） .By adding filter in front of the camera lens and setting different incision in the schlieren system , respectively , the influence of the plume flow field was observed .The experimental results showed that the filter and dark field schlieren could improve the display effect of the schlieren image .
