What is Influence of the Wavelength of Cut-In Sinusoidal Trailing Edge Shape to the Aerodynamics Characteristic of the Airfoil about?
The influence of the cut-in sinusoidal trailing edge shape with different wavelengths on the aerodynamics characteristic has been parametrically investigated by numerical unsteady RANS simulation, open-source code; Code\_Saturne. The results were compared with the benchmark baseline and blunt profile trailing edge shape. The geometry of NACA0012, NACA4412 and NACA4415 airfoil with a small modification to obtain a zero thickness trailing edge are selected as a baseline profile. The blunt trailing edge is a cut-offs at the trailing edge for 10% of the chord. Three wavelengths of sinusoidal trailing edge shape at 0.25c, 0.50c and 0.75c with 0.05c amplitude are selected, where c is the airfoil chord length. The flow is studied at high Reynolds numbers (Re) 10 6 for the angle of attack 5 degrees. The results show the change in lift and drag characteristics with changing of NACA profiles and the modified trailing edges.
