A multiphase model for exploring electrochemical Marangoni flow

open access: yesElectrochemistry Communications, 2023
A multiphase numerical model based on the volume of fluid (VOF) method is proposed to simulate the transient, electrochemically-generated Marangoni flow in a system comprising a NaOH electrolyte and a eutectic gallium–indium (EGaIn) metal droplet.

Dynamo Action in Magnetohydrodynamics and Hall‐Magnetohydrodynamics [PDF]

open access: yesThe Astrophysical Journal, 2003
The first direct numerical simulations of turbulent Hall dynamos are presented. The evolution of an initially weak and small-scale magnetic field in a system maintained in a stationary regime of hydrodynamic turbulence (by a stirring force at a macroscopic scale) is studied to explore the conditions for exponential growth of the magnetic energy.

Magnetic material in mean-field dynamos driven by small scale helical flows

open access: yesNew Journal of Physics, 2014
We perform kinematic simulations of dynamo action driven by a helical small scale flow of a conducting fluid in order to deduce mean-field properties of the combined induction action of small scale eddies.
