Summary
Results from large-eddy simulations (LES) of the spatial development of a shearless turbulence mixing layer are presented. The study is related to the mixing of two turbulent fields having different dominant length scales and levels of turbulent kinetic energy (excluding the effects of mean shear). In a French-German cooperation, different ways of providing proper inflow conditions are investigated: On the French side, an analytical pseudo-random inflow condition was created, and the spatial development of the mixing layer was calculated on a coarse grid using a newly developed two-equation subgrid scale model. On the German side, the inflow condition was provided by numerically simulating the effects of the two different parallel bar grids used in the experiment and the spatial development of the mixing layer was carried out on a very fine grid, together with the classical Smagorinsky subgrid scale model. The best results from LES on both sides show good mutual agreement as well as good agreement with experimental data from Veeravalli and Warhaft [1].
