In this study, we have examined the phenomenon of a bubble ascent in the presence of a vertically applied electric field. To simulate the problem, a novel electrohydrodynamic solver integrated with the open-source solver interFoam has been utilized. This solver incorporates the solution of the charge convection equation to determine the charge distribution and Coulomb force accurately. The effects of the electric capillary number \((Ca_E)\) and Bond number (Bo) on the bubble’s behavior under the imposition of an electric field have been investigated. As the bubble begins to rise, the electrical force exerted at the interface causes the bubble to deform in the vertical direction. It has been observed that higher values of \(Ca_E\) result in increased electrical forces, leading to greater deformation of the bubble. A transition from vertical to horizontal deformation is observed as Bo increases from lower to higher values. In the ellipsoidal regime, the electrical force effectively suppresses the bubble’s deformation. Moreover, due to the facilitation of bubble motion by the electrical force, the terminal velocity is higher when an electric field is present compared to its absence. An increase in both \(Ca_E\) and Bo corresponds to an increase in the terminal velocity.
