本文基于Taylor湍流扩散理论,利用北黄海5~#倾废区定点锚泊连续测流资料,计算了该区不同时间尺度的水平湍流扩散系数。计算结果表明,湍流扩散系数随时间尺度的变化较敏感;潮流因素对扩散系数的影响较大。要求在实际应用中根据研究对象尺度的大小来选择扩散系数。
Based on Taylor’s theory of turbulent flow diffusion, the continuous turbulence data of fixed points in the 5 ~ # dumping area of North Yellow Sea are used to calculate the horizontal turbulent diffusion coefficient at different time scales in this area. The calculated results show that the turbulent diffusion coefficient is sensitive to the variation of the time scale, and the influence of the flow factor on the diffusion coefficient is larger. It is required to select the diffusion coefficient according to the size of the research object in practical application.
