Top: time evolution of the streamwise velocity field in the near-wall region of wall-bounded turbulent flow; bottom: two dimensional slice of the streamwise velocity evolving in the wall-normal and streamwise directions. In a typical aerodynamics setting, these chaotic dynamics can occur in the first 6 millimeters above the aircraft wing.

Visual comparison of experiment and 3D simulation of thermal induced phase separation of gelatin and polyethylene-glycol. The spheres are approximately 50 microns in diameter. Experiment performed and captured by Dr. Vishwesh Shah of the Di Carlo Bioengineering Lab; simulation images courtesy of Dr. Eric Hester.

Cation concentration (top) and electric potential (bottom) in chaotic electroconvective 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.


Whitewater in the Merced River in Yosemite National Park, featuring multiphase, free-surface turbulent flow.
