Pengaruh Separasi Aliran Terhadap Kinerja Aerodinamika Airfoil Naca 0012

D Danardono Dwi Prija T

Abstract


Abstract : The aerodynamics performance and flow patterns of a model with a NACA 0012 airfoil section were studied experimentally in a sub sonic open wind tunnel. The pressure distributions were measured at various angles of attack and at the Reynolds number 4,98.104 based on the wing chord. Smoke generator was used for performing flow visualization. Data indicated that a laminer separation bubble was formed at 10o angle of attack and it reduced the value of cl/cd of the airfoil. Meanwhile the best aerodynamics performance was reached at 7o angle of attack.

Keywords : airfoil, flow separation, aerodynamics performance
