A multiphase model for exploring electrochemical Marangoni flow
Electrochemistry 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.

Magnetohydrodynamics as Superfluidity [PDF]
Physical Review Letters, 2019 We show that relativistic magnetohydrodynamics (MHD) can be recast as a novel theory of superfluidity. This new theory formulates MHD just in terms of conservation equations, including dissipative effects, by introducing appropriate variables such as a magnetic scalar potential, and providing necessary and sufficient conditions to obtain equilibrium ...

Dynamo Action in Magnetohydrodynamics and Hall‐Magnetohydrodynamics [PDF]
The 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.
