Direct numerical simulations are used to investigate the dynamics of a large spherical particle suspended in a developed homogeneous turbulent flow. A definition of the direction of slip is introduced and used to construct the mean fluid velocity profile around the particle. One observes that the carrier flow turbulence is calmed down in the wake of the particle.
