Numerical simulation of gas-liquid-solid Circulating Fluidized Bed (CFB)

Through summary of multiphase flow coupling, considerate the conservation of mass and momentum conservation, used the gas phase as a continuous phase, liquid phase and solid phase as dispersed phase, CFB has been simulated with the help of Eulerian model. It show that the local gas holdup increases from the computational domain inlet to the outlet, the local solid holdup decreases from the computational domain inlet to the outlet, and the local liquid holdup decreases from the computational domain inlet to the outlet.
