In this equation, atx= 1 (the trailing edge of the airfoil), the thickness is not quite zero. If a zero-thickness trailing edge is required, for example for computational work, one of the coefficients should be modified such that they sum to zero. Modifying the last coefficient (i.e. t...
Or the equation for obtaining drag force/coefficient can be rewritten differently? Ref.1: 1. C.L. Ladson, “Effects of Independent Variation of Mach and Reynolds Numbers on the Low-Speed Aerodynamic Characteristics of the NACA 0012 Airfoil Section,” NASA TM 4074, 1988....

Governing Navier–Stokes–Fourier equations of a slip velocity along the airfoil surface in the N-S-F calculations. A further investigation at M = 2.0 and AOA = 0-deg showed that In this section we present the governing equation and the this difference may be considerably reduced if the ...
The dynamic stall calculation method of airfoil inunsteady flow field is established by using Reynolds time-averaged N-S equation and standard k-ω model, and numericalcalculation is carried out by Fluent. The variation of the vortex, the upper and lower surface pressure and the lift...
This research paper presents the design and analysis of a NACA 0012 airfoil with a circular dent of 30 mm depth on its upper surface. The objective of this study is to investigate the effect of the dent on the airfoil's aerodynamic performance. The airfoil's geometry was modeled using a ...
