Time evolution of the streamwise velocity field in the near-wall region of wall-bounded turbulent flow.

Time evolution of the external electric field (black), fluid velocity (green/yellow), and charge distribution (blue/red) in an electrolyte model. The generation of the counter-rotating vortices in the presence of a time-varying electric field is referred to as alternating-current induced charge electro-osmosis.

Fluctuating hydrodynamics model of a room temperature ionic liquid (RTIL) 1-butyl-3-methylimidazolium hexafluorophosphate [DMPI+][F6P-] between two oppositely charged electrodes. The brain-like patterns result from a balance between electrostatic forces and interfacial tension.
