Abstract


In this paper the analysis of the two dimensional subsonic flow over a National Advisory Committee for Aeronautics (NACA) 8-h-12 airfoil at various inlet velocities (100,200,300,400,500 km/h) and operating at atmospheric conditions is presented. The standard k-epsilon model and steady state conditions have been considered for the 2D CFD analysis. The aim of the work was to show the behavior of the airfoil at these conditions and to establish a verified solution method. The computational domain was composed of 12150 cells emerged in a structured way, taking care of the refinement of the grid near the airfoil in order to enclose the boundary layer approach. Meshing of the geometry and specification of the boundary types have been accomplished using GAMBIT 2.3.16 and the analysis has been carried out using ANSYS FLUENT 6.2.16. An analytical study is done on the behavior of the airfoil subjected to various inlet velocities.
