Single-bubble EHD behavior into water two-phase flow under electric-field stress and gravitational acceleration using PFM

Abstract In this study, single-bubble electro-hydrodynamic effects on the two-phase laminar flow of water under electric field stress are investigated using numerical modeling. A 2D axisymmetric model is also developed to study the growth and departure of a single bubble. The phase-field method is a...
