摘      要：In order to grasp the particle flow characteristics and energy consumption of industrial fluidized spouted beds,we conduct numerical simulations on the basis of a Computational Particle Fluid Dynamics(CPFD)*** particular,the traction model of Wen-Yu-Ergun is used and different inlet conditions are *** a low-speed fluidizing gas,the flow state of the particles is better and the amount of particles accumulated at the bottom of the bed wall becomes *** the same air intake,the energy loss of a circular nozzle is larger than that of a square nozzle.
