3D FEM Simulation of Electrospinning Machine for the Study of Full-Scale Electrostatic Field on the Electrohydrodynamic Process

The paper presents a three-dimensional fully-detailed finite-element model of the commercial electrospinning machine FLUIDNATEK LE-100 developed in the commercial software Comsol MultiPhysics. The paper aims to assess the effect of the process parameters on the production stability with particular attention to the distribution of the electric field lines, especially at the tip of the needle and at the corners and edges of the collector. The results show specific influences of several parameters, and the model proves to be a viable tool to investigate aspects of interest raised by experimental experience.
