Query: Effect of energy spectrum law on clustering patterns for inertial
  particles subjected to gravity in Kinematic Simulation   We study the clustering of inertial particles using a periodic kinematic
simulation. Particles clustering is observed for different pairs of Stokes
number and Froude number and different spectral power laws ($1.4 \leqslant p
\leqslant 2.1$). The main focus is to identify and then quantify the effect of
$p$ on the clustering attractor - by attractor we mean the set of points in the
physical space where the particles settle when time tends to infinity. It is
observed that spectral power laws can have a dramatic effect on the attractor
shape. In particular, we observed a new attractor type which was not present in
previous studies for Kolmogorov spectra ($p=5/3$).
