摘　　要：基于Darcy理论模型和Navier-Stokes方程,应用过滤材料微观建模仿真软件GeoDict,结合三维电镜扫描设备生成的过滤材料切片照片,对过滤材料进行三维建模并仿真研究,研究内容为材料的流场特性、过滤效率与容尘能力,得到了过滤材料的渗透率、一定流速下的压力降、单次加灰的过滤效率以及多次加灰的效率和压力降变化.将仿真结果与过滤材料性能试验结果进行了对比分析,结果表明,其误差小于10%,具有良好的一致性.Based on the Darcy theory model and the Navier-Stokes equation, the filter material micro modeling simulation software GeoDict is applied to the filter material generated by the three-dimensional electron microscope scanning equipment, the three-dimensional modeling and simulation of the filter material are studied. The reasearch content are the flow field characteristics, filtration efficiency and the dust capacity of the material. The permeability of filtration material, the pressure drop at a certain velocity, the filtration efficiency of single dust addition, the efficiency and pressure drop of multiple dust addition are also discussed. The simulation results are compared with the performance test results of the filter material. The results of the simulation are in well agreement with the test results, and the error data is within the acceptable range of less than 10%.
