Abstract
Direct Numerical Simulations were performed for homogeneous isotropic turbulence laden with small dense particles. Coupling between the phases was done assuming that the particles obey Stokes drag law and are much more dense than the fluid. The ratio of the particle to fluid turbulence time scale was varied from 0.14 to 1.5 and the mass loading ratio was varied from 0.1 to 1.02. Moderate size particles were found to concentrate in regions of high strain rate and low vorticity and significant attenuation of turbulence energy was observed for mass loading ratios greater than 0.1. Attenuation was uniform across the spectrum rather than concentrated in specific frequency bands.
