Abstract
The analysis of flow around airfoil is of great importance in various sectors of practical interest, for example, the aviation industry, where appropriate projects are directly related to the concepts of efficiency and safety. This study aims to develop a methodology for proper discretization and analysis of flow in airfoils, using the software package ANSYS Inc. For this analysis drag and lift coefficients are compared to results of experimental data (Selig et al.,1995)of Eppler 423, Selig 1223 and NACA 2414 profiles for high Reynolds number. The turbulence models used in the numerical study are standard κ-ϵ model with an enhanced wall treatment and the κ-ω model SST also in order to evaluate the effectiveness of each model in calculating a turbulent flow. Also used if the turbulence model Reynolds Stress model followed by Sparlat Allmaras model and finally the presentation of the results obtained by comparing the models adopted.
