摘　　要：给出了适于浓密气固流化床的双流体力学模型，采用ICE和改进的IPSA算法，对均匀布风气固流化床中的流动特性进行了数值模拟，得到了均匀布风自由鼓泡流化床中的一种流动结构．计算结果与实验结果表明，所采用的计算模型和数值方法具有较高的可靠性．A two - fluid model for studying the fluid dynamics in a fluidized bed is presented. Numerical simulation is carried out for simulating the fluid dynamics in a bubbling fluidized bed with uniform air in-jected at the bottom of the bed. The ICE and IPSA algorithm is adopted to solve the coupled nonlinear equations. The distribution of liquid shape in the fluidized bed are obtained, and the simulation results agree well with the experimental results reported in literatures.
