Query: A lattice model for the Eulerian description of heavy particle
  suspensions   Modeling dispersed solid phases in fluids still represents a computational
challenge when considering a small-scale coupling in wide systems, such as the
atmosphere or industrial processes at high Reynolds numbers. A numerical method
is here introduced for simulating the dynamics of diffusive heavy inertial
particles in turbulent flows. The approach is based on the position/velocity
phase-space particle distribution. The discretization of velocities is inspired
from lattice Boltzmann methods and is chosen to match discrete displacements
between two time steps. For each spatial position, the time evolution of
particles momentum is approximated by a finite-volume approach. The proposed
method is tested for particles experiencing a Stokes viscous drag with a
prescribed fluid velocity field in one dimension using a random flow, and in
two dimensions with the solution to the forced incompressible Navier-Stokes
equations. Results show good agreements between Lagrangian and Eulerian
dynamics for both spatial clustering and the dispersion in particle velocities.
This demonstrates the suitability of the proposed approach at large Stokes
numbers or for situations where details of collision processes are important.
