چکیده
Airfoil is a fundamental geometry in designing various aerodynamic objects. Passive flow control installation essential determining the airfoil's performance. The influence of variations slat size as passive instrument analyzed using CFD method with Reynold number Re= 10^6 . NACA 6641 airfoil was used 10%c and 16%c. Based on computational results, have substantial efficiency airfoil. Variations additional C l ability to reach 20.6043% 13.1917%, respectively. In addition, 16%c can delay stall until it reaches AoA ≥ 19°. Meanwhile, 17°. However, also affect resulting drag force. Slat measuring addition d up 50.9252%. 10% c 21.8389%. lift-to-drag ratio curve, has lowest compared slat. highest level stability when without installation.

Aerodynamic Performance Enhancement of a NACA 66-206 Airfoil Using Supersonic Channel Airfoil Design
Supersonic channel airfoil design techniques have been shown to significantly reduce drag in high-speed flows over diamond shaped airfoils by Ruffin and colleagues. The effect of applying these techniques to a NACA 66-206 airfoil is presented. The design domain entails channel heights of 8-16.6% thickness-to-chord and speeds from Mach 1.5-3.0. Numerical simulations show an increase in the lift-...
متن کاملCFD study on NACA 4415 airfoil implementing spherical and sinusoidal Tubercle Leading Edge
The Humpback whale tubercles have been studied for more than a decade. Tubercle Leading Edge (TLE) effectively reduces the separation bubble size and helps in delaying stall. They are very effective in case of low Reynolds number flows. The current Computational Fluid Dynamics (CFD) study is on NACA 4415 airfoil, at a Reynolds number 120,000. Two TLE shapes are tested on NACA 4415 airfoil. The ...

متن کاملVerification of a CFD solver in near ground effect for aerodynamic behavior of airfoil NACA 0015
Numerical investigation was performed on NACA 0015 which is a symmetric airfoil. Pressure distribution and then lift and drag forces are verified. Changing of ground clearance was a considerable point. Also the angle of attack was changed from 0° to 10°. Pressure coefficient reaches its higher amounts on the wing lower surface when the ground clearance diminishes. Increment of the angle of atta...
