The objective of the thesis is to study the effect of the geometry modifications on the aerodynamic characteristics of a standard airfoil (NACA series). The Airfoil was chosen for a high aspect ratio and reynolds number of the range 10⁶ - 10⁷ (realistic conditions for flight and naval applications). Experimental and Numerical investigation were executed in collaboration with KTH – CTL and Schlumberger. Experimental investigations were conducted at NTNU which was funded by Schlumberger. The numerical investigation was executed with the massively parallel unified continuum adaptive finite element method solver “Unicorn” and the computing resources at KTH – CTL. The numerical results are validated against the experiments and against experimental results in the literature, and possible discrepancies analyzed and discussed based on the numerical method. In addition, this will help us to expand our horizon and get acquainted with the numerical methods and the computational framework. The further scope of this thesis is to develop and implement the new modules for the Unicorn solver suitable for the aerodynamic applications. / I arbetet studeras effekten av geometri-modifikationerpå aerodynamiska egenskaper hos en standard-vingprofil ur NACA-serien. Profilenvaldes för en slank vinge och Reynoldstal mellan en och tio miljoner vilket kanvara realistiskt för flygplan och marina tillämpningar. Experiment ochnumeriska beräkningar utförs i samarbete mellan KTH/CTL och Schlumberger.Experimenten utfördes på NTNU med stöd av Schlumberger. Beräkningarna gjordesmed finita-element paketet "Unicorn" på KTH/CTL s datorer. NyaUnicorn-moduler för aerodynamiska beräkningar utvecklas vilket ger erfarenhetav de numeriska metoderna och beräkningsmiljön. Numeriska resultat validerasmot experimenten och resultat i litteraturen, och avvikelserna för den aktuellanumeriska metoden analyseras
