  This review explores particle resuspension from surfaces due to fluid flows.
The objective of this review is to provide a general framework and terminology
for particle resuspension while highlighting the future developments needed to
deepen our understanding of these phenomena. For that purpose, the manuscript
is organized with respect to three mechanisms identified in particle
resuspension, namely: the incipient motion of particles (i.e. how particles are
set in motion), their migration on the surface (i.e. rolling or sliding motion)
and their re-entrainment in the flow (i.e. their motion in the near-wall region
after detachment). Recent measurements and simulations of particle resuspension
are used to underline our current understanding of each mechanism for particle
resuspension. These selected examples also highlight the limitations in the
present knowledge of particle resuspension, while providing insights into
future developments that need to be addressed. In particular, the paper
addresses the issue of adhesion forces between complex surfaces - where more
detailed characterizations of adhesion force distributions are needed - and the
issue of particle sliding/rolling motion on the surface - which can lead to
particles halting/being trapped in regions with high adhesion forces.
