Suction over the airfoil surfaces is formulated as the velocity boundary condition of the Navier-Stokes solver which uses the implicit approximate factorization scheme. As examples, the present method for LFC was applied to the NACA0012 airfoil at Mach numbers of 0.2 and 0.75. Computational results show that appropriate suction distribution brings about a large amount of recession of the boundary-layer transition point and a great deal or drag reduction., 資料番号: NALSP0007033, レポート番号: NAL SP-7}, title = {二次元翼の層流制御のNavier-Stokes解析}, year = {1986} }
