Under a Small Grant for Exploratory Research, an investigation will be conducted of species separation in a binary mixture. The species are smoke and air. Unusually rapid separation of smoke particles was observed in preliminary experiments in a vortex flow designed to study vortex breakdown. The process was much too rapid to be due to centrifugal separation, and is not explainable with conventional mechanisms. A further systematic exploration of the phenomenon, together with numerical particle path simulations, is to be carried out. A new mechanism for rapid species separation would be highly useful in separations technology for a broad range of engineering systems.

根据探索性研究的小额资助，将对二元混合物中的物种分离进行调查。 种类是烟雾和空气。在旨在研究涡流破坏的涡流初步实验中，观察到烟雾颗粒异常快速分离。这个过程太快了，不可能是由于离心分离造成的，并且无法用传统机制来解释。将对这一现象进行进一步的系统探索，并进行数值粒子路径模拟。 一种快速物质分离的新机制对于广泛的工程系统的分离技术将非常有用。
