Keywords: ;

Abstract: The work deals with an investigation of steady, laminar and incompressible flow inside a toroidal pipe. In particular, our aim is to investigate the effects of curvature and the Reynolds-number on the flow features. Numerical simulation are performed with the open-source CFD code OpenFOAM and the results are compared with the available data in the literature [Canton et. Al 2017, Int. J. Heat Fluid Flow]. The analysis shows that by increasing the curvature, the flow features are altered. This change in flow features becomes more important as the curvature increases. A complete description of friction factor and secondary flow quantities is provided, and a comparison with reference data allows to assess the reliability of OpenFOAM for this study case by providing results in an easier way than with more advanced codes such as Nek5000.
