衝撃波管による翼型まわりの密度分布の評価について

抄録

In this study, the CFD was performed to investigate aerodynamic characteristics of the supercritical airfoil (SC-0414) attached with Gurney Flap. The ANSYS FLUENT was used to simulate transonic airfoil flows. And the results were compared with the previous experimental results that was obtained by PDI (Point Diffraction Interferometer) flow visualization technique. The Mach number is M = 0.8, the Reynolds number is Re = 1.5×10⁵, respectively. The height of flaps are 1% (GF1%) and 3% (GF3%) chord length. As the results, the negative pressure of GF3% is larger than GF1% and clean condition. The characteristic showed the same trend with the previous experimental data.
