Issues associated with the development and realization 
of stochastic models of the impurity particle motion and scattering 
in a turbulent flow are considered. The proposed model is used to 
calculate turbulent flows of a low-concentration gas suspension in 
channels and jets. We compare the results of the calculations obtained 
from the viewpoint of different models and the results of numerical 
simulation with the data in which the influence of turbulent pulsations 
on the particle motion was ignored.
