Abstract: The intensity fields of vortex formation and the range of the Reynolds numbers were calculated by the computer simulation during water movement at different velocities in the diffuser/confuser and at certain distances before and after the hydraulic resistance in the pipeline. It is determined that transition of the laminar regime to the turbulent regime of water movement in the pipeline after the confuser and the diffuser occurs at velocity of 2 and 3 m/s, respectively. Intensity of vortex formation does not change with increasing flow velocity of fluid in the confuser. Flow expansion leads to an increase in intensity of vortex formation with increasing flow velocity of fluid.
Key words: the diffuser, the confuser, vortex formation, the Reynolds number, water, flow velocity.
