Computational interferometry for three-dimensional flow

  • 摘要: 计算干涉技术通过试验图像和计算图像相比较,可以验证CFD的有效性,是研究复杂流场的有力工具。作者根据M-Z干涉仪的光学成像原理,用计算机仿真实现了将数值计算获得的二维、轴对称和三维的复杂流体的密度场转换为“无限条纹”和“有限条纹”的干涉图像,尤其是在处理三维流场时,采用流场重构的方法,达到了很好的效果。
    Abstract: In present paper,a technology (including a computed optical device and digital image process) of computational interferometry for complicated 3-D steady and unsteady flow is described.A good agreement between computational holographic interferogram for 3-D shockwave flow and experimental ones shows that this technology is a powerful tool for CFD and experimental research in complicated 3-D flows.
