Theorists described an inertial lift of particles in microchannels

A group of scientists from MSU, Frumkin Institute of Physical Chemistry and Electrochemistry of the Russian Academy of Sciences, and Juelich Research Center have described the mechanism of appearance of an inertial lift force acting on finite-sized particles in microchannels. Such calculations were previously possible only for some specific cases. A more accurate description allows one to use this inertial lift for particle sorting. The study was published in Journal of Fluid Mechanics.
