The article reflects the technology of improving the quality of the grid area with its symmetrization in numerical modeling of three-dimensional (3D) turbulent flow in small tubular apparatus (MTA). Performed step by step technique to improve the grid area, demonstrated by the example of 3D modeling of fluid flow in the pipe MTA - mixer. Decisions made in the software package Fluent. In the numerical experiment, the results obtained are close to the experimental data of other authors.
