Description An axisymmetric Dual-Grid Level-Set Method (DGLSM) is proposed for transient simulation of two-fluid electrohydrodynamic flow. Level-set and electric field equations are solved on a uniform grid which is twice that for Navier-Stokes equations, for accurate computation of interface and forces due to surface tension and electric field. Code validation and performance study is done for two problems: coalescence and electric field-induced deformation of drops (both fluids leaky and perfect dielectrics). The DGLSM gives results of almost the same accuracy as a fine-grid-based traditional level-set method (LSM) in a computational time slightly more than that for a coarse-grid-based LSM.
