Numerical Simulation of Turbulent Swirling Flows

In this paper, turbulent swirling flow in circular pipe in the wake behind an axial fan is investigated by URANS and LES using two different CFD codes: SPARC, developed at Institute of Fluid Machinery, at Karlsruhe Institute of Technology and OpenFOAM. Results of simulations are compared with experimental results obtained with LDA measurement techniques in that flow field. (© 2013 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim)
