dc.description.abstractIn the present work, wall-resolved Large Eddy Simulations (LES) of incompressible turbulent flows are presented for a convergent-divergent channel with adverse pressure gradients. The paper presents comparative results for different Reynolds numbers, studying wall friction coefficients and turbulent kinetic energy budgets from LES computations. The turbulent kinetic energy budgets are investigated at the separation and at re-attachment points. The CFD code used in this work is based on the incompressible Navier-Stokes equations, solved for structured grids with a semi-spectral methodology. The simulations performed are wall-resolved and the WALE subgrid scale model is used for turbulence closure. The analyses of the turbulent kinetic energy budgets find specific distribution patterns, respectively, at separation and re-attachment points.en
