摘要： Gas-solid two-phase turbulent flows, mass transfer, heat transfer and catalytic cracking reactions are known to exert
interrelated influences in commercial fluid catalytic cracking(FCC) riser reactors.In the present paper, a three-dimensional
turbulent gas-solid two-phase flow-reaction model for FCC riser reactors was developed. The model took into account the gas-
solid two-phase turbulent flows, inter-phase heat transfer, mass transfer, catalytic cracking reactions and their nterrelated
influence. The k-V-kp two-phase turbulence model was employed and modified for the two-phase turbulent flow patterns with
relatively high particle concentration. Boundary conditions for the flow-reaction model were given. Related numerical
algorithm was formed and a numerical code was drawn up. Numerical modeling for commercial FCC riser reactors could be carried
out with the presented model.
