单漏口多颗粒同时放出时松散介质的流动规律

FLOW LAW OF GRANULAR MATERIALS AS MANY GRAINS SIMULTANEOUSLY FLOWING THROUGH A HOPPER

当漏口直径等于颗粒粒径时,B.B库里柯夫的松散介质流动理论对理想松散介质的流动规律有较完善的研究结果,而当漏口直径大于颗粒粒径时,他只得出了移动场中漏口中线上的颗粒的概率分布离散函数。本文用随机数学推出理想松散介质多个颗粒从漏口同时放出时,移动场中任意点的颗粒下移概率的离散函数,将该函数连续化后,得出松散介质的一些流动规律及其表述方程。

As the diameter of a drawn grain was equal to the diameter of the hopper, there were excellent theoritical research results about the flow of perfect granular material which were derived by Coliekov with random but, when the diameter of a hopper was larger than the drawn grain's, he just put forth the function of probability for the grains to move down in the vertical median of the hopper. So, this paper provides functions of probability with which the probability can be calculated for the grains in all the...
