| Abstract: | For the 90°circular-section bend pine of the dust removal equipment, a computational fluid dynamic （CFD） model is established on the basis of the incompressible Reynolds-averaged Navier-Stokes equations. The numerical simulation of the evaluation index for flow field characteristics in pipeline is achieved by using the Realizable k-ε turbulence model, and by applying the control volume method and the structured grid for performing discretization and standard wall function for modification in the near-wall region. |
