A Study on the Dynamics of Fibrous Aerosals in Filtration

拟议的项目是关于使用核孔和纤维过滤器过滤纤维状气溶胶。纤维倾向于与水流对齐，并穿透过滤器。滤光片中的纤维取向将使用为亚微米直径的超细纤维开发的全息和图像处理技术来确定。结果将与过滤效率测量结果进行比较，并辅之以理论模型。该项目将在过滤器中纤维运动的微观机械方面提供独特的实验结果，并在环境控制、半导体工业、生物和医学科学中应用。

The proposed project is on the filtration of fibrous aerosols using nuclepore and fibrous filters. Fibers tend to align with the flow and penetrate the filters. The fiber orientation in filter will be determined using holographic and image processing techniques developed for ultrafine fibers with submicron diameters. The results will be compared with filter efficiency measurements complemented with a theoretical model. The project will provide unique experimental results on the micromechanical aspects of a fiber motion in a filter and filter efficiency, with application in environmental control, semiconductor industry, biology and medical sciences.
