ANSYS-Fluent software represents a CFD software having the capability for solving various engineering flow problems. Besides offering a variety of flow solvers, this software also offers various type of turbulence model can be used in the flow analysis. The present work focuses on the use of this software applied to two type wing models, a moderately swept wing and (2) a rectangular wing planform. The moderately swept wing geometry and experimental data were obtained from AGARD AR-138, whereas the rectangular wing planform was obtained from RTO-TR-026. The first model evaluated by using five different turbulent models, namely (1) Spalart-Allmaras, (2) k-ε Standard, (3) k-ε Realizable, (4) k-ω Standard and (5) k-ω SST turbulence models. Comparisons result with AGARD shows that all turbulent models are able to provide in a good agreement. However, Spalart-Allmaras and k-ω SST turbulence models give less CPU time than the others. These two turbulent models then applied to the case of a rectangular wing plan form. The result from the second test case, the k-ω SST turbulence models, give a more accurate result compared to the Spalart-Allmaras turbulence models. It gives a better result compared with the Spalart-Allmaras turbulence models. The k-ω SST turbulence model makes the ANSYS-Fluent result just differ 11.5% from the experiment result while for the Spalart-Allmaras turbulence model differs 14.05%. Here it can be concluded that k-ω SST turbulence mode may represent a suitable turbulence model for solving flow over a rectangular wing to the moderate swept wing plan form
