The Physics of Sediment Transport Initiation, Cessation, and Entrainment Across Aeolian and Fluvial Environments (2020, background): “…Viscous Damping Binary collisions that occur within an ambient fluid can be significantly damped depending on the Stokes number St ≡ s |vr |d/(9νf ) [Gondret et al., 2002; Yang and Hunt, 2006; Schmeeckle, 2014; Maurin et al., 2015], where vr is the relative particle velocity just before a…”
Collision modelling for the interface-resolved simulation of spherical particles in viscous fluids (2012, methodology): “This was indeed observed in the experiments of Gondret et al. (1999, 2002) as displayed by the symbols in figure 7(b) below.”
On aeolian transport: Grain-scale interactions, dynamical mechanisms and scaling laws (2011, background): “Gondret et al. (1999, 2002) have performed experiments in which spherical beads rebound on a planar solid inside fluids of different densities and viscosities.”
Lagrangian-Eulerian methods for multiphase flows (2013, background): “In a recent review article [1], Fox notes that the NDF representation of the particle phase constitutes a mesoscopic approach that offers a clear separation between physical and mathematical approximations.”
Rheological stratification in experimental free-surface flows of granular–liquid mixtures (2005, result): “2001) or horizontal floor (Gondret et al. 2002), the above observations are consistent with the elastohydrodynamic analysis of Davis et al.”
