On fluid–particle dynamics in fully developed cluster-induced turbulence (2015, background): “Experimental measurements by Aliseda et al. (2002) of heavy particles in decaying homogeneous isotropic turbulence suggested that clusters act as large pseudo-particles that add to the settling velocity of the particles inside them.”
Large-eddy simulation of particle-laden turbulent flows (2008, background): “The behaviour of heavy particles in homogeneous isotropic turbulence has been studied experimentally by Aliseda et al. (2002) and numerically by Bosse, Kleiser & Meiburg (2006) where it is shown that the settling velocity is enhanced by the turbulence and that large temporal and spatial inhomogeneit”
Sedimentation of a dilute suspension of rigid spheres at intermediate Galileo numbers: the effect of clustering upon the particle motion (2014, methodology): “This idea was suggested by an anonymous referee in analogy to the model proposed by Aliseda et al. (2002) for the enhancement of the settling velocity of sub-Kolmogorov-size droplets due to clustering in grid-generated turbulence.”
Two-way interaction between solid particles and homogeneous air turbulence: particle settling rate and turbulence modification measurements (2005, methodology): “Recently, Aliseda et al.

Droplet growth in warm turbulent clouds (2012, result): “Aliseda et al. (2002) and Yang and Shy (2005) show enhanced particle-settling velocities which are consistent with the numerical work of Wang and Maxey (1993). Gerashchenko et al. (2011) show the strong effects of gravity on the selective transport of particle sizes by changing the orientation of th”
Turbidity Currents and Their Deposits (2010, background): “Whereas both experimental (Aliseda et al. 2002, and references therein) and computational (Bosse et al. 2006, and references therein) investigations of particles in homogeneous turbulence suggest that particle settling should be enhanced by twoway coupling effects, turbidity-current experiments and…”
Experimental and numerical investigation of inertial particle clustering in isotropic turbulence (2008, background): “Particle clustering can influence a broad range of aerosol processes, such as particle settling (Wang & Maxey 1993; Aliseda et al. 2002), evaporation/condensation (Shaw et al. 1998), and interparticle collisions (Wang, Wexler & Zhou 2000). Sundaram & Collins (1997) identified the radial distribution”
Towards initial mass functions for asteroids and Kuiper Belt Objects (2010, background): “A complementary process is vertical settling of clumps formed at high altitude, which brings material to lower altitudes faster than would otherwise be the case (Wang and Maxey, 1993; Aliseda et al., 2002; Bosse et al., 2006).”
The effect of Reynolds number on inertial particle dynamics in isotropic turbulence. Part 2. Simulations with gravitational effects (2015, background): “…‘preferential sweeping’ or ‘fast tracking’ of particles (particles sampling downward-moving fluid over upward-moving fluid) had been observed in DNS (Wang & Maxey 1993; Yang & Lei 1998; Ireland & Collins 2012; Bec et al. 2014) and earlier experiments (Aliseda et al. 2002; Yang & Shy 2003, 2005).”
Analyzing preferential concentration and clustering of inertial particles in turbulence (2012, methodology): “In Lasheras team (Aliseda et al. (2002)), this has been employed to point out that clustering effect is maximum at scales of order 10gK.”
Settling regimes of inertial particles in isotropic turbulence (2014, background): “This ‘fast-tracking’ (or ‘preferential sweeping’) effect has been observed in DNS of simple flows (Maxey 1987; Dávila & Hunt 2001; Hill 2005) and turbulence (Wang & Maxey 1993; Yang & Lei 1998), and in experiments (Nielsen 1993; Aliseda et al. 2002; Yang & Shy 2003, 2005).”
