Jet speed in bubble rupture

Abstract

When a polymer bubble is broken in the bubble electrospinning process, thou-sands of thousands jets are produced with almost same initial ejecting speed, which plays a very important role on the formation of the nanofiber. In this pa-per, the nanofiber membranes were prepared by the bubble spinning with differ-ent air temperatures. This paper also gives a simple mathematical model to pre-dict the initial speed of jets, and it is as high as 300 m/s.
