“…Initially, the extruded polymer melt at the tip of the nozzle is like a truncated spherical droplet which changes its shape after the introduction of the electric field. Though there are geometrical models for electrospinning process such as Taylor cone as a frustum and straight jet as a cylinder are discussed in literature [5,8,21,22,25]. In our modeling, the jet pulled out from droplet is geometrically defined as a funnel as shown in Figure 1 which consists of a cone whose tip is removed surmounted on a narrow cylinder is discussed.…”

“…Although brilliant results have been achieved in terms of microstructure physical properties such as crystallinity, there is a need to design more practical models to control the desired microstructure topographical properties of electrospun fibers. For instance, Zhmayev and Joo have a model which analyzese the polymer melt behaviour of nylon through its flow induced crystallization properties [22,23]. In another work by Zhmayev, the stable jet region in melt electrospinning has been reported [22].…”

“…Therefore, in the case of a Taylor (Lee et al, 2011) vortex, the shear and elongation stress from the pair of oppositely rotating vortices align the solute molecules while they move in a radial direction. Such flow-induced nucleation was already observed in the melt spinning of polymers (Zhemayev et al, 2010), where a high shear during melt spinning initiated polymer nucleation, resulting in a high crystalline polymer product. Thus, the induction of stable crystals with a Taylor vortex occurred within 8 h at a low rotation speed of 300 rpm and within 4 h when increasing the rotation speed to 1,000 rpm.…”

“…Mathematical modelling approaches can be used to predict the topographical dependency of microfiber scaffolds on various operational parameters for better understanding of melt electrospinning technique through the use of numerical studies and comparing the results with experimental data [17,22,25,26]. We have previously shown that the topographical properties of melt eletcrsopun scaffolds had directed stem cell differentiation into neural phenotypes [9].…”

“…To achieve a scaffold that provides specific mechanical and topographical properties, mathematical models have been developed to predict the effect of key operational parameters such as nozzle size, temperature, collecting distance and applied voltage on controlling the fiber size and porosity [17,[25][26][27]. Although melt electrospining has shown its promising potential in tissue engineering applications, controlling scaffold topography, however, still remains challenging [9,14,20,21].…”
