| 摘 要： | 由风力扬起的粉尘是由不同粒径所组成的颗粒群，能否用数值方法再现出不同粒径的颗粒群的运动轨迹是预测含尘质量分数的前提和关键。从研究粉尘粒子在空间中的受力情况及在这些力作用下的运动状态，通过研究粉尘在紊流气流中的扩散规律，得出粉尘颗粒的运动轨迹，为最后达到粉尘控制奠定基础。

| Abstract: | As dust engendered by wind power is a dust group of different sizes, the premise and key factor of predicting quality fraction of the dust load is whether we can reproduce the moving path of dust groups of different sizes under a numerical scheme. This article probes into the force conditions of the dust in the air and its moving state under the force. Through studying the regular dust diffusing patterns in turbulent air stream, the moving path of the dust can be worked out and thus lay a foundation for the dust control. |
