Analyzing preferential concentration and clustering of inertial particles in turbulence (2012, background): “Note that investigations of the so-called two-way coupling problem are still scarce (see Ferrante and Elghobashi, 2003; Lucci et al., 2010, 2011 for the most extensive numerical studies) and much remains to be understood on the influence of the loading.”
Observations of Small-Scale Turbulence and Energy Dissipation Rates in the Cloudy Boundary Layer (2006, background): “Other balloon-borne measurements were reported by Gerber (1986), Blanc et al.”
An Updated Classification Map of Particle-Laden Turbulent Flows (2006, methodology): “The physical mechanisms responsible for the above observations are discussed in detail in [ 8 ] and thus will not be repeated here.”
Turbulent channel flow of dense suspensions of neutrally buoyant spheres (2014, background): “Even if the macroscopic flow is viscous and laminar, inertial effects at the particle scale may induce shear-thickening (Kulkarni & Morris 2008b; Picano et al. 2013) or normal stress differences (Zarraga, Hill & Leighton 2000). This change of the macroscopic behaviour is due to a strong modification”
Large-eddy simulation of particle-laden turbulent flows (2008, methodology): “Ferrante & Elghobashi (2003) have shown how micro-particles reduce the decay rate of turbulence kinetic energy whereas large particles enhance it compared to particle-free turbulence.”
Interface-resolved direct numerical simulation of vertical particulate channel flow in the turbulent regime (2008, methodology): “Using this methodology, some of the mechanisms of turbulence modulation through local accumulations of particles has been elucidated in wall-bounded shear flow (Pan and Banerjee, 1996), homogeneous shear flow (Ahmed and Elghobashi, 2000) and homogeneous isotropic turbulence (Squires and Eaton, 1990;”
Modulation of isotropic turbulence by particles of Taylor length-scale size (2010, methodology): “Note that Ψp(t) can act as a source or sink of TKE as was shown by Ferrante & Elghobashi (2003), whereas ε(t), by definition, is always a sink of TKE.”
Large-eddy simulation of swirling particle-laden flows in a coaxial-jet combustor (2003, background): “Past computational work has focused on particle–turbulence interactions in simplified geometries (Ferrante and Elghobashi, 2003; Maxey et al., 1994; Maxey and Patel, 2001; Eaton and Fessler, 1994).”
Two-way interaction between solid particles and homogeneous air turbulence: particle settling rate and turbulence modification measurements (2005, background): “The presence of these scarce heavy particles would have little influence on fluid turbulence (Ferrante & Elghobashi 2003).”
On fluid–particle dynamics in fully developed cluster-induced turbulence (2015, background): “Ferrante & Elghobashi (2003) showed that trajectory crossing of large particles through turbulent eddies creates local gradients in the fluid due to particle drag, causing the turbulence to become anisotropic, with a reduced decay rate of turbulence kinetic energy as compared to the unladen case.”
