Numerical Simulation of Flow Field in Pulsating Fluidized Bed Under special entry conditions, the CFD is used to simulate the three-dimension fluidized bed with different oscillation intensity and frequency in order to research the effect of sound oscillation on flow field in the fluidized bed. The results indicate that the sound oscillation can make the distribution of the flow field more uniform and can promote the heat and mass transfer.

脉动流化床流场模拟在特定的入口条件下，应用计算流体力学技术对三维流化床在不同振动强度、不同频率扰动作用下的流场进行模拟，得到声波扰动对流化床流场分布的影响，结果表明声波振动可以使流化床内的流场分布更加均匀，促进热质传递。
