Numerical approach to controlling a moving jet’s vibration in an electrospinning system: An auxiliary electrode and uniform electric field

A variational principle is established for a moving jet in the electrospinning process to study the vibration property of the jet. A higher accelerated velocity and lower vibration frequency are needed in a multi-needle electrospinning system. This paper introduces an auxiliary electrode to enhance the electric strength, and a numerical analysis is carried out to design an optimal electric field.
