Abstract

In this paper, the results of an international collaborative test case relative to the pro-duction of a Direct Numerical Simulation and Lagrangian Particle Tracking database forturbulent particle dispersion in channel flow at low Reynolds number are presented. Theobjective of this test case is to establish a homogeneous source of data relevant to the generalproblem of particle dispersion in wall-bounded turbulence. Different numerical approachesand computational codes have been used to simulate the particle-laden flow and calculationshave been carried on long enough to achieve a statistically-steady condition for particle distri-bution. In such stationary regime, a comprehensive database including both post-processedstatistics and raw data for the fluid and for the particles has been obtained.
