Using what has become a celebrated catchphrase, Philip W. Anderson once wrote that
“more is different”(Science, Vol. 177, Issue 4047, pp. 393–396, 1972). First formulated in the …

This article deals with the resuspension phenomenon whereby particles adhering on a wall
surface can be re-entrained by a flowing fluid. This is an area where significant progress has …

Ellipsoidal particle transport and deposition in dilute turbulent channel flows are studied.
The instantaneous fluid velocity field is generated by the direct numerical simulation (DNS) …

Physical cleaning techniques are of great concern to remove particulate contamination
because of their low environmental impact. One of the promising candidates is based on …

Face masks have been adopted as an essential measure to prevent transmission and
spread of the virus infection during the pandemic of Covid-19. The present study evaluates …

We study the incipient motion of single spheres in steady shear flow on regular substrates at
low particle Reynolds numbers. The substrate consists of a monolayer of regularly arranged …

Investigations on the respiratory transport and deposition of airborne asbestos, man-made
vitreous fibers (MMVFs), and carbon nanofiber/carbon nanotubes have been actively …

Image-processing has been used in granular systems for detecting particle positions and
motion near optically accessible surfaces like sediment flow and bedload transport. We …

We study incipient motion of single beads on regular substrates made of spherical particles
of a different size in steady shear flow at small particle Reynolds numbers. We cover a large …

In the present paper, analytical formulae for the shear lift forces on nanocylinders moving in
linear shear flows in the free molecule regime are derived on the basis of the gas kinetic …
