2D modeling of Forcespinning(TM) nanofiber formation with experimental study and validation.

摘要

A newly developed method of producing nanofibers, called Forcespinning(TM), has proven to be a viable alternative to mass produce nanofibers. Forcespinning(TM) utilizes centrifugal forces which allow for a host of new materials to be processed into nanofibers while also providing a significant increase in yield and ease of production. To improve and enhance the Forcespinning(TM) production method, a 2D computational Forcespinning(TM) fluid dynamics model is developed. Three computer models, namely time-independent and time-dependent inviscid models and a viscous model are obtained and the influences of various parameters on Forcespinning(TM) fiber formation are obtained. This work also presents a detailed explanation of this new fiber production method using high speed photography to capture the jet initiation process and to track the trajectories of the resulting jets. The effect that the controllable parameters have on the fiber trajectories and final fiber diameters are presented, and a comparison to theoretical calculations is made.
