The inlet boundary condition is an important element of the hydrodynamic behavior of the bubbling fluidized bed. Based on the Euler-Euler gas-solid two-fluid model, numerical simulation of bubbling fluidized bed with jet center inlet was studied. Using the pulse and steady velocity inlet boundary conditions, the formation, grow-up and separation of bubbles in the bubbling fluidized bed was analyzed and researched. Compared with the experimental result from Kuipers, the result of simulation shows that it is more reasonable to forecast and analyze the hydrodynamic behavior with the turbulence of the velocity inlet.
