GOALI: Nanofibers in Coalescer Filter Media

cts - 9900949 g。目的是在微观和宏观上评价除常规纤维外，使用纳米纤维过滤亚微米颗粒和液滴的过滤介质的性能。纳米纤维将通过静电纺丝产生。将比较不同过滤器配置的压降和颗粒捕获效率。将确定两种流动模式（液滴/颗粒流动和通过多孔介质的扩散）之间的阈值。研究了光纤电学特性和光纤充电特性对聚结效率的影响，以及声场对聚结效率的影响。这是阿克伦大学和AirMaze公司以及其他六家公司之间的一个GOALI（学术联络与工业的资助机会）合作项目，这些公司将为该项目提供实物和现金捐助。该研究与过滤技术相关，从洁净室技术到水净化膜都有应用。

CTS-9900949G. Chase, D.H. Reneker, and S. Linnersten, U. of AkronThe objective is microscopic and macroscopic evaluation of the performance of filter media for sub-micron particles and droplets using nanofibers in addition to the regular fibers. Nanofibers will be generated by electrospinning. The pressure drop and particle capture efficiency will be compared for various filter configurations. The threshold between two flow patterns, droplet/particle flow and diffusion through porous medium, will be determined. The effect of fiber electrical properties and fiber charging, as well as the effect of acoustical fields on coalescence efficiency will be investigated. This is a GOALI (Grant Opportunities for Academic Liaison with Industry) collaborative project between the University of Akron and AirMaze Corporation and a group of other six companies which will provide both in kind and cash contributions to the project. The research has relevance for filtration technology, with applications from clean room technology to water purification membranes.
