| The article presents the results of numerical analysis of turbulent flow and hydraulic losses in the rotary section of the pipeline with the different radius of rotation. There are several items under investigation the structure of arising secondary flow (longitudinal vortex pair), the longitudinal strength of the vorticity pattern transforming normal vorticity at the tube surface in combination with the transverse pressure gradient in the longitudinal vorticity, which depends on the turning radius using a fixed Reynolds number. |

KEY WORDS: modelling of turbulent flows, turbulent flow in a curved pipe, pair longitudinal vortex, wall friction |
