The purpose of this dissertation is to validate the k –ω turbulence model using the OpenFOAM software package. The validation process compares the results simulated through computational fluid dynamics (CFD) with theoretical or experimental data in order to check the ability of the model to reproduce physics. This will be done by using three different airfoils. An airfoil is the general name for the cross sections of profiles suited for wings, blades or sails. When a fluid passes from this profile, a force perpen-dicular to the motion is generated (Lift) and a force in the direction of the motion (Drag). The effects of variations in angle of attack and Reynolds number on the lift and drag component will be investigate. The validation will happen by comparing the OpenFOAM output with the calculated data of the NREL and with the results of the XFOIL software.
The decision was made to investigate S816 S817 and S1818, developed by the National Renewable Energy Laboratory (NREL). This family of thick laminar-flow airfoils was developed for 30 to 40 meter horizontal axis wind turbines (HAWT). The S816 is the primary airfoil, S818 the root airfoil, and S 817 the tip airfoil.
