Simulation of the scattering and deposition of dispersed-phase 
particles in the region of interaction of a turbulent flow with an 
obstacle is considered. The regimes and distinctive features of deposition 
of particles in the vicinity of a critical point are investigated 
under different conditions. The sedimentation coefficient of the impurity 
is calculated as a function of the parameters of unperturbed flow 
and the particle size. The results of the calculations are compared 
to the data obtained without allowance for the influence of the fluctuations 
of the carrier-flow velocity on the motion of the impurity.
