Numerical Simulation of Steady Jet in the Electrospinning Process
The electrospinning process uses electrical force to produce nanofibers.Because electrospinning jets have high-speed and complex movement in high-voltage electrostatic field, and very small diameter, it is hard to study electrospinning jet with experiments.Hence,numerical simulationwas used and aimed to understand jet movement under different spinning conditions.Compared with other software used in computational fluid dynamics(CFD),we choose POLYFLOW to simulate steady jet movement in 2D space,and use GAMBIT to build geometric model and plot grid.The simulation results indicate that when solution volumetric flow rate was kept constantjet diameter became thin easily with increasing draw force.But when draw force was too great,there were rough knot and suddenly thinning appeared along jet.When draw force reached a value, stable jet disappeared during electrospinning.
