In A Nutshell Scientists discovered a previously unknown form of mixing that occurs when large groups of dense particles ...
A large-scale fluid simulation tracking 100,000 particles as they settle through turbulent water has identified a previously unknown convective mixing effect at the leading edge of the particle cloud.
Pollutant particles with a smaller diameter, density, and flow rate can enter the deep lung, but large particles with a low density may also enter the deep airways, according to a study. Researchers ...
