Abstract:Taking the complex influences of two-phase flow, heat transfer, mass transfer, and cracking reactions into account, a 3-D gas-solid two-phase flow-reaction CFD model for vortex reactor was established based on gas-solid two-phase turbulent flow model and kinetics of reactions. Related numerical solution was formed and numerical simulation was carried out to show the details of flow, heat transfer, mass transfer and reactions in the vortex reactors.
