A stationary isothermal model of the aerodynamics of a 
two-phase flow in an axisymmetric channel has been constructed with 
allowance for the turbulent and pseudoturbulent mechanisms underlying 
the transfer of the solid phase momentum. The equations of dispersed 
phase motion are closed at the level of the equations for the second 
moments of the pulsation velocities of particles, whereas the equation 
of momentum transfer of the carrier is closed on the basis of a one-parameter 
model of turbulence extended to the case of two-phase turbulent flows. 
The results of calculations are compared with experimental data.
