Research Initiation: Effects of Microscopic Environment on the Morphology of Growing Clusters

这项研究涉及到当单个小颗粒附着在种子颗粒或预先存在的聚集体上时形成的聚集体模式的计算机建模。它将探讨布朗扩散到聚集体的输运速率和附着速率具有相当量级的状态。将发展离散粒子的模拟和连续分布粒子的模拟。聚集体形态可以极大地影响颗粒聚集体的特性，包括它们的光学、流变性和堆积性。这项研究有助于将团聚体形态与运输和生长动力学联系起来。

This research involves computer modeling of the patterns of aggregates formed when individual small particles become attached to a seed particle or to a preexisting aggregate. It will explore the regime where the rate of transport by Brownian diffusion to the aggregate and the rate of attachment are of comparable magnitude. Simulations regarding the particles as discrete objects and simulation regarding particles continuously distributed will be developed. Aggregate morphology can greatly influence the characteristics of particle agglomerates including their optical, rheological, and packing properties. This research should help relate agglomerate morphology to the transport and growth kinetics.
