Unsteady Compressible Flow past an Airfoil near the Moving Surface

파형 곡면 위를 비행하는 2차원 WIG익형의 비정상 압축성 유동 해석

A two-dimensional airfoil flying over a wavy wall is calculated by solving the unsteady Euler equation. Unsteady Transonic flow over an NACA00012 airfoil in pitching motion has been computed for code validation. Some numerical results for NACA6409 airfoil under different wave number, wave length, fly height are presented. The numerical results show the variation of lift and pitching moment coefficients are increased as wave length decrease.
