| 摘 要： | 根据紊流扩散理论提出了计算井巷紊流传质过程中径向紊流扩散系数和纵向弥散系数的方法,该法使得这一难以进行实验研究的问题有可能进行实验研究,而且适用于其他几何形状不规则的空间和明渠的紊流传质,用此法实验,结果证明了作者给出的井巷紊流传质的径向紊流扩散系数和纵向弥散系数的理论模式和扩散效应是弥散效应千分之一的预想。

| Abstract: | In this paper a method is developed for calculating the radius turbulent diffusion coefficient and longitudinal dispersion coefficient in mine mass transfer based on the theory ef turbulent diffusion. This method not only makes it possible to conduct the experimental research for problems which were difficult to investigate in laboratories but also can be used to investigate the turbulent mass tranfer process in open channel and space with irregular shape.Experiments conducted in wind tunnel in laboratory by using this method have showed a good agreement between theoretical and experimental resultalts and proved that the dispersion effect is more than 1000 times as strong as that of the diffusion in mine turbulent mass transfer. |
