In this paper, turbulent swirling flow in circular pipe is numerically investigated using OpenFOAM, an open-source CFD software. Flow is computed as 2D axisymmetric, with various turbulent models, but with main accent on computations with Reynolds stress transport models. Two Reynolds stress models were used in computations: Launder-Gibson (LG) and Speziale-Sarkar-Gatski (SSG) models. Previous author?s experimental results are used as a validation tool for numerical computations. It was shown that standard two-equation models can?t predict the flow in right manner, while the Reynolds stress models give good prediction of mean velocities. As a part of research SSG model is implemented in OpenFOAM code.
