Two-Particle Dispersion in Isotropic Turbulent Flows (2009, background): “This led Chun et al. (2005) to introduce a new model for the rate-ofstrain tensor that relaxes this assumption.”
The effect of Reynolds number on inertial particle dynamics in isotropic turbulence. Part 2. Simulations with gravitational effects (2015, methodology): “Chun et al. (2005) found that large accelerations can contribute to higher relative velocities between unlike particles, leading to higher collision frequencies. Finally, one especially promising finding of this study is that by extending the model of Zaichik & Alipchenkov (2009) and using DNS data ”
Droplet growth in warm turbulent clouds (2012, methodology): “For bidisperse droplets, (12) can be extended to (Chun et al., 2005; Ayala et al., 2008b) g12(r) = C0 ( η2 + r2D r2 + r2D )C1/2 , where rD is a parameter representing the diffusion-like process.”
Acceleration statistics of heavy particles in turbulence (2005, background): “In parallel with the experimental effort, theoretical analysis (Balkovsky, Falkovich & Fouxon 2001; Falkovich & Pumir 2004; Bec, Gawedzki & Horvai 2004; Zaichik, Simonin & Alipchenkov 2003) and numerical simulations (Boivin, Simonin & Squires 1998; Reade & Collins 2000; Zhou, Wexler & Wang 2001; Chu”
Experimental and numerical investigation of inertial particle clustering in isotropic turbulence (2008, background): “Theoretical investigations have yielded predictions of the RDF under a variety of assumptions (Falkovich, Fouxon & Stepanov 2002; Zaichik & Alipchenkov 2003; Chun et al. 2005). All of the results suggest that inertial clustering could profoundly influence the evolution of the size distribution of a ”
The effect of Reynolds number on inertial particle dynamics in isotropic turbulence. Part 1. Simulations without gravitational effects (2015, methodology): “This surprising result is consistent with other DNS (Collins & Keswani 2004; Chun et al. 2005; Salazar & Collins 2012a). Our data also show that both τ(2) η 〈S(2)〉 and τ(2) η 〈R(2)〉 decrease with increasing Rλ for St 1, in agreement with Collins & Keswani (2004). We use the formulation given in Chun”
Dynamics and statistics of heavy particles in turbulent flows (2006, background): “Recently, much effort have been devoted to the study of phenomena related to preferential concentration of inertial particles in turbulent flows by means of both theoretical [12, 13, 14, 15] and computational [16, 17, 18, 19, 20, 21] approaches.”
Growth of Cloud Droplets in a Turbulent Environment (2013, methodology): “Using DNS data, Ayala et al. (2008a) extended the work of Chun et al. (2005) to include empirically the effect of gravity.”
