“…The simulation results of the dissipative particle dynamics of the spinning process show that an increase in the rotation speed leads to a decrease in the fiber diameter and an increase in the yield. [ 72 ] The simulation results also show that the molecular chain length first increased and then decreased with an increase in speed. The experiment for preparing PEEK fibers was consistent with the above simulation results, but the stretching time was reduced owing to the excessively high rotating speed, resulting in the incomplete evaporation of the solvent and the increase in the fiber diameter.…”

“…Long and continuous nanofibers are then produced under the joint stretching of the electric field force, viscous resistance of air, and gravity. [ 72 ] The stretching force is combined with the forces in the axial and tangential directions, [ 73 ] which results in a superior stretch effect on the jet compared to electrospinning alone. Compared with electrospinning, the jet in centrifugal electrospinning has bending instabilities with fewer frequencies and amplitudes ( Figure a).…”

“…investigated the effects of spinning factors on fiber properties (diameter, yield, and molecular chain formation) using DPD. [ 31 ] They found that in an electrostatic field, a change in the rotational speed, temperature, and electric field strength is inversely proportional to the fiber diameter. At the same time, it is proportional to the fiber yield and chain length.…”

“…The entire jet can be modeled as a chain of charged particles connected by visco-elastic links with one another as, e.g., in works of Reneker et al [4] or Lauricella et al [24,25]. Mesoscopic modeling incorporating individual polymer chains was performed by Liu et al [26][27][28][29], who employed the dissipative particle dynamics to model polymer melt electrospinning using a coarse-grained model of chains. The dissipative particle dynamics was also applied by Joulaian et al [30] to model the initial stages of the formation of the Taylor cone.…”
