Abstract

We present a brief overview of a numerical study of the dispersion of particles in stably stratified turbulence. Three types of particles arc examined: fluid particles, light inertial particles ($\rho_p/\rho_f = \mathcal{O}(1)$) and heavy inertial particles ($\rho_p/\rho_f \gg 1$). Stratification suppresses the vertical dispersion of all three types of particles compared to isotropic turbulence. The horizontal dispersion, on the otherhand is enhanced. The importance of the forces that act on inertial particles are examined and the results are shown for particles with $\rho_p/\rho_f = 10$. The inertia of the particles results in a nonuniform particle distribution over the domain. This preferentia concentration effect is presented here for heavy particles, and it is found that the effect is stronger in isotropic turbulence than in stratified turbulence.
