Compressible unsteady inviscid flows around airfoils are analyzed by integrations of time-dependent Euler equations using finite difference techniques. Numerical solutions are obtained through an explicit upwind scheme with local time steps using a locally refined, boundary modified square grid of Cartesian coordinates. In this grid, the boundary conditions at curved airfoil surfaces are precisely defined by the finite difference. Numerically calculated results demonstrate two-dimensional applications for a transonic flow around a symmetrical airfoil in a free-flight condition. Other calculations for a low-speed flow around a large thickness airfoil and variations with flap and spoiler were made in a wind tunnel boundary condition. Comparisons of pressure distributions and lift coefficients were also made with other calculated solutions and with experimental data.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
