An enriched finite element/level-set model for two-phase electrohydrodynamic simulations

In this work, a numerical model for the simulation of two-phase electrohydrodynamic (EHD) problems is proposed. It characterized by physically consistent treatment surface tension as well jump in electric material properties. The formulation based on finite element method enriched with special shape functions, capable accurate capturing discontinuities both fluid pressure and gradient potential. Phase interface is, thus, represented zero-thickness boundary. proposed methodology allows modeling force an interfacial one, strictly abiding physics. approach tested using droplet deformation benchmarks. Moreover, application to study three-dimensional (3D) case, not symmetry revolution, shown. defines basis wide range EHD problems.
