Abstract: Abstract A numerical simulation of the formation of droplets from an electrified capillary using the Boundary Element Method (BEM) is presented. An incompressible and perfectly conducting liquid is injected from a capillary into a dynamically inactive and insulating gas. Assuming an irrotational liquid flow, the problem consists in coupling the BEM resolution of two Laplace equations: for the velocity potential inside the fluid domain and for the electric potential in the capacitor gas gap. The motion of the free surface is determined by the Bernoulli’s equation resulting from the normal stress balance on the free surface.
