摘要
利用三维粒子动态分析仪(3D- PDA) 测得了矩形截面三分支联接的三维速度分布。在测量中,经过理论分析与对比试验,选择了蚊香烟雾作为散射粒子。实验结果揭示了三分支管的一些流动特性。
The three dimensional velocities of the manifold junction with rectangular section are measured by use of three dimensional particle dynamic analyzer(3D-PDA).Mosquito repellent incense smoke is selected as scattering particles in the measurement by means of theoretic analysis and making contrast experiments.The results reveal some flow characters of manifold junctions,which lay the foundation of further study of turbulent flow for manifold junctions.
