The aerodynamic performance of a 3-D NACA 6409 wing in ground effect was examined numerically with different wing configurations. The influence of changing twist angles, anhedral angles, taper ratios, and sweep angles on the aerodynamic performance was examined and compared with based model. Structured mesh domains were built, and RANS turbulence m...

... structured H mesh was used all over the domain, except for the free tip surface, where an unstructured mesh was implemented as shown in Figure 2.The mesh achieved a minimum orthogonal quality of 0.3981 in few cells on a scale of 0 to 1. Y-plus (Y+) values were kept into the logarithmic law region; (Y+) >30. Spalart-Allmaras turbulence model was selected to be used, as it was proved to have the best agreement with experimental results if compared to other turbulence models as shown in Figure 3, according to (Jung et al. 2008) and ( Djavareshkian et al. 2011). ...

The goal of this paper is to study numerically the flow physics of a fountain formed by twin-jet impingement on ground. The incompressible Reynolds-Averaged Navier-Stokes (RANS) equations with realizable k-ε and WA (Wray-Agarwal) turbulence model are employed in the numerical simulations with ANSYS Fluent. A series of numerical simulations for stra...

Recent studies have demonstrated that periodic spanwise modifications of the Trailing Edge of an airfoil can significantly reduce the noise produced and can also increase its aerodynamic performances. This study aims to analyse the effects of such modifications on the aerodynamic performances of a profile by numerical simulation, with a particular...
