Abstract

The paper deals with verification of the mathematical model of electrospinning devices. The model enables to simulate the electric field strength and voltage with using the finite element method. The simulation could be used mainly in the design of the spinning device for electrospinning process. Boundary conditions introduced into the mathematical model were obtained from an experiment on the functional model. The experiment was based on the Taylor’s theory of the critical potential. Thanks to the FEM analysis it was found the value of the critical field strength and the place where the critical field strength appears on the polymer drop. The analysis results were compared with analytical calculation. The presented mathematical model can facilitate development of the electrospinning devices. The model could be used for design optimisation of the spinning electrodes as well as the design of the whole electrospinning apparatus. Moreover, the model might be applied for setting of optimal technological parameters for producing modern nonwoven textile products.
