详细

An analysis of the potential for the use of modern computer technologies in the study of the hydrodynamics in the workspace of devices by means of numerical methods using the Salome–Meca numerical simulation preprocessor for model creation, the Code–Saturne processor for calculation of hydrodynamic models, and the Paraview post-processor for display and analysis of the results is presented. The range of applicability of laminar, k−ε, and k−ω SST turbulent models of fluid flow for simulation of the hydrodynamics of an incompressible fluid in the workspace of a test model with different Reynolds numbers is revealed based on a comparison of the present results with results of analytical calculations. Use of the k−ω SST turbulence model for simulation of the workspace of mixers with internal diameter from 50 to 200 mm in the range of Reynolds numbers from 7 · 10³ to 2 · 10⁶ with number of grid cells greater than 2 · 10⁵ is recommended.
