When a stationary droplet containing a solute in a volatile solvent evaporates, the flow in the droplet can assemble into complex patterns. Researchers have examined such transport in evaporating sessile droplets in solvents. ...
A naturally occurring injection of underground fluids drove a four-year-long earthquake swarm near Cahuilla, California, according to a new seismological study that utilizes advances in earthquake monitoring with a machine-learning ...

A pair of fluid dynamics physicists, one with Ecole Polytechnique, the other the University of Canterbury, have used their respective backgrounds to develop the optimal way to fry a crêpe. In their paper published in the ...
Using data from field experiments and modeling of ground faults, researchers at Tufts University have discovered that the practice of subsurface fluid injection used in 'fracking' and wastewater disposal for oil and gas exploration ...
