Abstract: The computer calculation of water and industrial oil flow in the pipeline with the diffuser was implemented in the article. Comparison of changing the cell Reynolds number, pressure, and velocity of fluids flow in the conditions of laminar and turbulent regimes was made. It is found that characteristics of fluids during laminar flow and turbulent flows according to the Algebraic yPlus and L-VEL models are almost identical. Maximum intensity of the vortex flows formation is observed at the outlet of the expanding part of the pipeline during laminar water flow and according to the Algebraic yPlus, L-VEL and Spalart-Allmaras turbulence models. Flow of industrial oil in the pipeline with the diffuser practically does not lead to the vortex flows formation.
Key words: water, industrial oil, the pipeline, laminar flow, the turbulence model, the diffuser, velocity.
