AN INVESTIGATION ONTO JET PERTURBATION SIMULATION IN ELECTROSPINNING PROCESS

In the recent years, electrospinning is used as an efficient and simple method for producing nanofibers. The efforts of researchers have mainly focused on producing nanofibers from varied polymers and their application. But, little attention has been done in the process of electrospinning. The most important part of electrospinning is how to control the process by studying its instability. In this study, by using Reneker s model (bead-spring model), the dynamic behavior of electrospun jet fluids in the whipping instability was investigated by momentum equation. The governing equations were numerically simulated and the results were presented in plots. In these plots, jet perturbation formation was shown step by step.
