摘 要:The molten liquid flow inside a packed bed is a familiar momentum transportation phenomenon in a blast furnace.With regard to the reported mathematical models describing the liquid flow within a packed bed,there are some obstacles for their application in engineering design,or some limitations in the model itself.To overcome these problems,the forces from the packed bed to the liquid flow were divided into appropriate body and surface forces on the basis of three assumptions.Consequently,a new mathematical model was built to present the liquid flow inside the coke bed in a blast furnace.The mathematical model can predict the distribution of liquid flowrate and the liquid flowing range inside the packed bed at any time.The predicted results of this model accord well with the experimental data.The model will be applied considerably better in the simulation on the ironmaking process compared with the existent models.
