Extreme Events in the Dispersions of Two Neighboring Particles Under the Influence of Fluid Turbulence
Extreme Events in the Dispersions of Two Neighboring Particles Under the Influence of Fluid Turbulence
We present a numerical study of two-particle dispersion from point sources in three-dimensional incompressible homogeneous and isotropic turbulence at Reynolds number $\mathrm{Re}\ensuremath{\simeq}300$. Tracer particles are emitted in bunches from localized sources smaller than the Kolmogorov scale. We report the first quantitative evidence, supported by an unprecedented statistics, of the deviations …
