Electrospun Nanofiber Scaffold Simulator

Electrospinning is the workhorse technique for building the porous, fibrous scaffolds used across tissue engineering — vascular grafts, wound dressings, cartilage and bone scaffolds, and drug-eluting membranes. This simulator drives a real N-body electrodynamic model of the charged jet: individual jet segments feel Coulomb repulsion from their neighbors, an applied-field force toward the grounded collector, viscoelastic spring tension, and drag, and the resulting bending (whipping) instability is what actually stretches and thins the jet on its way down. Because the polymer volume is conserved along the jet, the live stretch ratio directly sets the fiber diameter, and every fiber that lands builds up a genuine random non-woven mat on the collector — the same scaffold morphology real electrospinning rigs produce. Tune voltage, flow rate, tip-to-collector distance and solution viscosity to see how each process parameter pushes fiber diameter up or down.
