Abstract Using the Reynolds averaged Navier-Stokes equations and the standard k-ε turbulence model,numerical simulations based on parallel computation were performed for three-dimensional turbulent flows containing longitudinal vortex pairs.The N-S equations were discretized by finite element method.The unstructured grid method was used to generate mesh.Characteristics of 3D velocity field were discussed.The numerical results of the mean-flow velocity were compared with the corresponding measurement data and good agreement was obtained.The results verify that the standard k-ε model can basically simulate the 3-D turbulent flow introduced by vortex generators.
