Abstract: | A two-dimensional stationary model of motion, heat and mass exchange, and chemical reaction of polydisperse coke and ash particles
in ascending gas-suspension flow has been constructed with allowance for the turbulent and pseudoturbulent mechanisms of transfer
in the dispersed phase. The system of equations that describes motion and heat transfer in the solid phase has been closed
at the level of the equations for the second moments of velocity and temperature pulsations, whereas the momentum equations
of the carrying medium have been closed using the equation for turbulent gas energy, which allows for the influence of the
particles and heterogeneous reactions. |
