A numerical investigation was carried out in this research work using finite volume Reynolds-Averaged Navier-Stokes Equations (RANSE) code ANSYS CFX, Validation was carried out by using experiments. The experimental and the numerical results concluded that the lift to drag ratio decreased with the increasing of the ground clearance.
Aug 09, 2017 · The variation of lift and drag coefficient with angle of attack is shown below for a NACA 0012 and NACA 6412 profile (you can plot the profiles yourself using the NACA 4 Series Plotting Tool). The aerodynamic data was compiled using a tool called xFoil for a Reynolds Number equal to 1 million.

Experimental Investigation of Lift forNACA 2412 Airfoil without Internal Passage with NACA 2412 Airfoil with Internal Passage in a Subsonic Wind Tunnel Consider the data for the NACA 2412 airfoil given in the figure below. From the figure estimate the lift and moment about the quarter chord (per unit span) for this airfoil when the angle of attack is 4° and the free-stream is at standard sea level conditions with a velocity of 50 ft/s (15.2 m/s). The chord of the airfoil is 2 ft (0.61m). 3.2For the NACA 2412 airfoil, the data in Fig 2.6a shows that, at α = 6 °, c l = 0.85 and c mc / 4 =− 0.037. In Example 2.4, the location of the aerodynamic center is calculated as x a. c c =− 0.0053, where x a.c is measured relative to the quarter-chord point.

The linear strength vortex panel method was first validated against thin airfoil theory and experimental data for a single NACA 2412 airfoil. At 2 degrees angle of attack, the linear strength vortex panel method predicted a Cl of about 0.49. Experimental data and thin airfoil theory gave Cl estimations of 0.45 and 0.22 respectively.

SUMMARY Wind tunnel tests have been conducted on an NACA 2412 air­ foil section at Reynolds number of 2.2 x 10 6 and Mach number of 0.13. Detailed measurements of flow fields associated with turbulent boundary layers have been obtained at angles of at­ tack of 12.4°, 14.4°, and 16.4°. The airfoil is assumed to have a chord length(c) of 1.0 meters (all dimensions in this module are in the standard MKS system of units), with the leading edge of the airfoil at (0,0,0) and the trailing edge at (1,0,0). The computational domain extends far upstream of the airfoil (8*c) where the boundary condition will be a velocity inlet. This NACA airfoil series is controlled by 4 digits e.g. NACA 2412, which designate the camber, position of the maximum camber and thickness. If an airfoil number is NACA MPXX e.g. NACA 2412
