Flow Field Analysis and Numerical Simulation for Dynamic Filtration with Rotating Disks

摘要

Dynamic filtration with rotating disks is modeled by three-dimensional graphics software and its flow field is analyzed and numerical simulated by CFD software.The mechanical stability of dynamic filtration with rotating disks in the work process is analyzed by the model of rotating flow.The results show that the farthest end of rotating disks exit the largest flow velocity.There are two circular flows,which can remove the pollutants of rotating disks.The pressure of water is gradually increased as the main flow is near cylinder of the filtration.Simulation results are consistent to the practice,which provides important theoretical basis for improving and optimization of dynamic filtration with rotating disks.
