摘要
本文运用了PIV实验与PHOENICS数值模拟相结合的方法,测量了不同聚合物浓度时的速度分布,并对实验结果以及模拟结果进行了对比总结,得到了幂律流体在环空管道中的流动规律,既偏心度对环空轴向速度的影响以及在环空宽窄间隙处,紊流核心区轴向速度分布,实验结果以及模拟结果基本吻合。
This thesis measures the velocity distribution of different concentration polymer, combining with the experiment of PIV and numerical simulation of PHOENICS, and comparing the results of the experiment with simulation obtains flow pattern of power law in the eccentric pipeline. The law bout the influence of eccentric degrees for axial velocity in width space and narrow space and axial velocity distribution in turbulent nuclear area, finally it＇s proved the results of PIV experiment and PHOENICS numerical simulation are basically consistent.
