当生长的晶体聚集时,它们聚集的速度取决于碰撞频率和碰撞效率。在本文中,我们重新审视 Mumtaz 的工作,从第一原理出发证明效率取决于 Mumtaz 的无量纲强度 M。 Mumtaz 的原始工作仅限于相同尺寸粒子之间的碰撞、简单张力下的失效以及源自接触点的碰撞。目前的工作将该方法扩展到包括多分散系统、剪切应力和线性接触。在所有研究的情况下,效率曲线的位置都在 Mof O(1) 处,而效率的分布取决于失效机制和接触几何形状。首先近似,两个碰撞粒子的碰撞效率取决于它们尺寸的几何平均值。这里介绍的工作提供了结晶器中某一点的聚集动力学。需要进一步的实验工作来确定哪种失效机制是合适的、相关材料特性以及对容器进行平均的适当方法。
When growing crystals aggregate, they do so at a rate that depends on the frequency of collisions and the efficiency of those collisions. In this paper we revisit the work of Mumtaz to show from first principles that the efficiency depends on Mumtaz's dimensionless strength,M. Mumtaz's original work was restricted to collisions between particles of the same size, to failure under simple tension and to collisions originating with a point of contact. The current work extends that approach to include polydisperse systems, shear stress and linear contacts. In all cases studied the location of the efficiency curve is atMof O(1), while the spread of efficiency depends on the mechanism of failure and the contact geometry. To a first approximation the efficiency of collision of two colliding particles depends on the geometric mean of their sizes.The work presented here provides aggregation kinetics at a point in a crystallizer. Further experimental work is required to determine which failure mechanism is appropriate, the relevant materials properties and an appropriate method for averaging over a vessel.
