A Simple Model for Solvent Evaporation in Electrospinning Process

Abstract

One of the most important issues in electrospinning process is whipping instability and solvent evaporation that plays a critical role in nanofiber formation. This report simulates whipping process using numerical methods for a bead-viscoelastic element fiber model combined with a polynomial equation for adding solvent evaporation influence on the three-dimensional path. The suggested equation has been obtained by applying Newton interpolation polynomial operation. Then the results of nanofiber diameters for experimental data, original model and modified model are compared with different statistical methods. ANOVA analysis shows the prediction of diameters could be more accurate and meaningful. Meanwhile, a calculation forecast accuracy chart is presented in detail. It is observed that our suggested model shows more accuracy and is more reliable than the bead-spring model.
