Electrospinning Jet Whipping Instability

This simulator models the electrically-driven bending (whipping) instability that turns a charged polymer jet into a nanofiber during electrospinning. A chain of charged beads is emitted continuously from a Taylor cone under an applied electric field, integrated in real time with Coulomb self-repulsion between jet elements, a viscoelastic spring-dashpot resisting stretch, and a surface-tension term that straightens local curvature — exactly the competition of forces that produces the real process's chaotic 3D whip. Adjust the field strength, charge density, solution stiffness and flow rate to see how each one controls the instability's onset, envelope size and the resulting fiber diameter at the collector.
