Effects of some numerical formulation aspects in high-lift configuration simulations

High-lift configuration aerodynamics are evaluated through different theoretical and numerical setups with CFD++ tool. Meshes are constructed with y+ ≈ 1 for typical configurations, in order to represent daily-production engineering applications. Aspects such as preconditioning, turbulence modelling, and cell-reconstruction polynomials are compared in terms of aerodynamic coefficient prediction and simulation convergence. A best-practice setup is achieved with successful prediction of wind-tunnel reference results.
