Direct numerical simulation of horizontal open channel flow with finite-size, heavy particles at low solid volume fraction (2013, background): “The majority of available numerical studies on particle-turbulence interaction are based on the point-particle approach (see e.g. Rouson and Eaton, 2001; Marchioli and Soldati, 2002; Narayanan, Lakehal, Botto, and Soldati, 2003; Picciotto, Marchioli, and Soldati, 2005).”
Physics and modelling of turbulent particle deposition and entrainment: Review of a systematic study (2009, methodology): “In turn, unbalanced fluxes lead to non-uniform (preferential) distribution of particles within the flow and produce near-wall particle accumulation (Reeks, 1983; Marchioli and Soldati, 2002).”
Direct numerical simulation of particle wall transfer and deposition in upward turbulent pipe flow (2003, methodology): “In this paper, we will also provide new insights into the physical link between particle transfer mechanisms and turbulence structures in the light of previous results obtained for plane channel flow (Marchioli and Soldati, 2002).”
Can turbophoresis be predicted by large-eddy simulation? (2005, background): “4,5 In these numerical simulations the ﬂuid is modeled as a continuous phase, while for each particle an equation of motion is imposed.”
Influence of gravity and lift on particle velocity statistics and transfer rates in turbulent vertical channel flow (2007, background): “On average, this repelling lift force prevents particles from reaching the wall unless they are entrained by strongly coherent in-sweeps ( Marchioli and Soldati, 2002 ).”
Exact regularized point particle method for multiphase flows in the two-way coupling regime (2014, background): “In these conditions the Stokes number Stη = τp/τη controls the dynamics of the disperse phase in terms of its preferential spatial accumulation, either small scale clustering in homogeneous flows [42, 28, 4, 29, 37] or turbophoresis in wall bounded flows [34, 25].”
Interface-resolved direct numerical simulation of vertical particulate channel flow in the turbulent regime (2008, methodology): “In particular, conditional averaging of wall-normal particle motion based upon the type of the surrounding flow structures (similar to the point-particle study of Marchioli and Soldati, 2002) should provide valuable insight.”
