⚡ Electrospray: Onset Voltage, Cone-Jet Regime, Rayleigh Charge and Droplet Size (2D needle-plate view)

Side view of an electrospray needle above a collector plate. Set voltage, flow, surface tension, conductivity, viscosity, gap and nozzle size, and see the onset voltage, dripping, cone-jet and multi-jet regimes, droplet diameter, charge against the Rayleigh limit, drift speed and spray current. Uses the reduced-order module of the 3D page, with four in-page numerical checks.
