Assessment of turbulence models for a wing-in-junction flow

Abstract

The numerous engineering applications involving wing-in-junction-flows make knowledge of the predictive effectiveness of turblance models for such flows valuable. The performance of eight turbulance models was asessed for a wing-in-junction flow test case using incompressible Reynolds-averaged Navier-Stokes (RANS) simulations. The case geometry consisted of an airfoil with a 3:2 elliptical leading edge, attached at the point of maximum thickness to a NACA 0020 series tail, mounted on a flat plate. The numerical results for pressure velocity and turbulend kinetic energy achieved using the various turbulence models were evaluated by comparison with experimental measurements published in the literature. It was found that the Realisable k-E model, and second-moment closure models, produced the closest agreement to the experimental data.
