| 摘 要： | 采用热线风速仪与系统平均法测定和研究了三种圆柱形封闭容器内的扬尘诱导湍流衰减特性，并与球形爆炸容器内已测定的扬尘诱导湍流衰减特性进行了比较。探讨了扬尘装置、容器体积、形状对扬尘诱导湍流瞬态特性的影响。实验结果显示，在粉尘等容燃烧容器内扬尘诱导湍流强度随时间的衰减特性具有一定相似性，它们均呈负指数关系。

| Abstract: | The hot wire anemometer measurement and ensemble average method were employed to determine the feature of dispersion induced turbulence during the transient dispersion process in three closed cylindrical explosion vessels. The comparison between the turbulent parameters from different vessels is presented. The influence of the dispersion system, volume and shape of vessels on the turbulent decaying feature is discussed. The results of Measurement show that among the decaying features of turbulence in three vessels, a similar pattern of negative exponent law exists. |
