Profiles of electrified drops and bubbles

摘要: Axisymmetric equilibrium shapes of conducting drops and bubbles, (1) pendant or sessile on one face a circular parallel-plate capacitor (2) free surface-charged, are found by solving simultaneously the boundary problem consisting augmented Young-Laplace equation for surface shape Laplace electrostatic field, given potential. The is nonlinear method finite element algorithm employing Newton iteration, modified frontal solver, triangular as well quadrilateral tessellations domain exterior to drop in order facilitate refined analysis sharply curved tips seen experiments. stability limit predicted this computer-aided theoretical agrees with
