The linear disturbance equations are cast on a fixed, body-intrinsic, curvilinear coordinate system. Those nonparallel terms which contribute mainly to the streamline-curvature effect are retained in this formulation and approximated by their local finite-difference values. Convex wall curvature has a stabilizing effect, while streamline curvature is destabilizing., 資料番号: AA0004167012, レポート番号: NAL SP-18}, pages = {51--53}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {Curvature effects in three-dimensional boundary layers}, volume = {18}, year = {1992} }
