GOALI: Nanofibers in Coalescer Filter Media

CTS-9900949G。本研究的目标是对除常规纤维外还使用纳米纤维的亚微米颗粒和液滴过滤介质的性能进行微观和宏观评估。纳米纤维将通过静电纺丝产生。对不同过滤器结构的压降和颗粒捕集效率进行了比较。将确定液滴/颗粒流动和在多孔介质中扩散两种流动模式之间的阈值。将研究纤维电学性质和纤维充电的影响，以及声场对聚结效率的影响。这是一个由阿克伦大学和AirMaze公司以及其他六家公司组成的GALI(学术与工业联系赠款机会)合作项目，将向该项目提供实物和现金捐助。这项研究与过滤技术有关，应用范围从洁净室技术到净水膜。

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.
