ON THE APPLICATION OF LARGE-EDDY SIMULATION TO PARTICLE-LADEN FLOWS

Resumo

A priori and a posteriori evaluation of the effect of the unresolved, subgrid, scales on the deposition of heavy particles are carried out. The deposition statistics obtained from the direct simulation of turbulent channel flow are compared with the results of two large-eddy simulations. Although the small scales, which are not resolved in the large-eddy simulations, are found to affect significantly the settling velocity, other quantities (the deposition rate and the distribution of the settled particles) are predicted accurately.
