摘要: The work discusses the linear and nonlinear stability of cylindrical surface deformations between two incompressible fluids. interface is carrying a uniform charge. inner fluid assumed to be liquid jet. Both fluids are modeled as special type Newtonian viscous fluid. Furthemore, effect adsorption taken into account. dielectric discussed in presence constant electric field axial direction. analysis performed along lines multiple scale perturbation expansion with additional slow time space variables. various criteria both analytically numerically. results displayed many plots showing parameter planes. show dual role negative rate change tension concentration surfactant on system stability, steps. theory, when used investigate jet, appears accurately predict new unstable regions.
