A stationary isothermal system of equations defining the 
behavior of a two-phase rising flow in the region of steady motion 
of a gas suspension in an axially symmetric channel has been developed. 
The equation of motion of the carrying medium is closed using a one-parameter 
model of turbulence, and the equation of momentum transfer in the 
dispersed phase is closed with the use of the equations for the second, 
third, and fourth moments of the pulsation velocities of the particles. 
The main mechanisms of two-phase turbulent flows were numerically 
investigated.
