A finite-difference method with third-order upwinding are employed without using any turbulence model. Also multi-directional method is used. Unsolved problems in computation around an airfoil are attacked and new results are presented, which will make the possibility of computational approach widen substantially. Using the same approach, a concept of an airfoil of negative thickness is introduced. Application of this concept is suggested., 資料番号: AA0000685052, レポート番号: NAL SP-34}, pages = {295--300}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {Simulation of subsonic flow past an airfoil}, volume = {34}, year = {1997} }
