【 摘 要 】

In this work, we study electrically induced flows numerically using open-source software and experimentally. Two systems are considered - single and multiphase (free surface) flows driven by axisymmetric DC and AC current injection. We investigate characteristic velocity and free surface deformation dependence on the injected current and validate it with experimental data. Results show that maximum axial velocity is a linear function of injected current, but free surface deformations are approximately proportional to current squared.
