The effect of Reynolds number on inertial particle dynamics in isotropic turbulence. Part 2. Simulations with gravitational effects (2015, background): “ ‘crossing trajectories,’ or ‘the sling eect,’ causes a departure from r2-scaling in the second-order structure functions at small separations, and can lead to large relative velocities (Yudine 1959;Falkovich et al. 2002;Wilkinson & Mehlig2005;Wilkinson et al. 2006;Falkovich & Pumir2007). (A”
Experimental and numerical investigation of inertial particle clustering in isotropic turbulence (2008, background): “Falkovich et al. (2002) argued that clustering-enhanced collisions may compensate for the lower efficiency of smaller droplets.”
Droplet growth in warm turbulent clouds (2012, methodology): “Falkovich et al. (2002) proposed a semi-analytical kernel that includes the effects of clustering of droplets and local fluid acceleration due to cloud turbulence and showed that cloud turbulence could substantially accelerate the formation of large droplets.”
Growth of Cloud Droplets in a Turbulent Environment (2013, background): “Falkovich et al. (2002) found that turbulence-induced inertial effects (in particular, droplet clustering) can substantially accelerate droplet growth over the condensation-coalescence size gap.”
Dynamics and statistics of heavy particles in turbulent flows (2006, background): “We consider particles much heavier than the carrier flow in the limit when the Stokes drag force dominates their dynamical evolution.”
Spectral (Bin) microphysics coupled with a Mesoscale Model (MM5). Part I: Model description and first results (2005, background): “Recent theoretical studies indicate that the turbulence effect is underestimated in the model, especially for drops with sizes of about 40–70 mm (e.g., Pinksy and Khain 1998; Wang 2001; Falkovich et al. 2002).”
Acceleration statistics of heavy particles in turbulence (2005, background): “…in diesel engines (Post & Abraham 2002) or some rocket propellers (Villedieu & Hylkema 2000), the formation of rain droplets in warm clouds (Pinsky & Khain 1997; Falkovich, Fouxon & Stepanov 2002; Shaw 2003) or the coexistence of plankton species (Rothschild & Osborn 1988; Lewis & Pedley 2000).”
The effect of Reynolds number on inertial particle dynamics in isotropic turbulence. Part 1. Simulations without gravitational effects (2015, background): “Other researchers have suggested that caustics become more prevalent at high Reynolds numbers, leading to larger relative velocities and thus more frequent particle collisions (Falkovich et al. 2002; Wilkinson et al. 2006).”
Analyzing preferential concentration and clustering of inertial particles in turbulence (2012, background): “Such process is for instance considered as a possible mechanism to understand rain initiation in warm clouds, where no clear explanation has emerged yet to explain the rapid growth rate of the droplets prior to rain (Shaw, 2003; Falkovich et al., 2002).”
Motion of inertial particles with size larger than Kolmogorov scale in turbulent flows (2008, background): “This effect has been the subject of intensively studies as it is closely related to the formation of rain from water droplets in cloud turbulence [7, 8].”
