摘要: Numerical simulation on the flow, heat transfer and cracking reactions in commercial fluid catalytic cracking(FCC)riser
reactors were carried out employingthe developed turbulent gas-solid two-phase flow-reaction model for FCC riser reactors
given in Part Ⅰ of thepresent paper.Detailed information about the turbulentflow fields in the riser reactor obtained
revealed the basic characteristics of the gas-solid two-phase turbulent flows when heat transfer and catalytic cracking
reactions were co-existing in the riser. Results showed that the distributions of the flow, the turbulence kinetic energy and
the catalyst particle concentration arenot uniform in the axial, radial and tangential directions. The most complicated part
of the riser reactor is the feed injecting zone. The complicated configuration of the turbulent gas-solid two-phase flows
would exert a great influence on the results of interphase heat transfer and cracking reactions.
