Flow variables on a large number of grid points are hardly defined by spatiotemporally limited amount of measurement data that poses an underdetermined problem. In this study we conduct sensitivity analysis of a vortex flow field by the use of an adjoint method. The idea of optimal/targeted observation in meteorology which aim to effectively determine a flow state by limited observations is interpreted in fluid dynamic problems where unsteady flows of much smaller scales are of interest., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0062070015, レポート番号: JAXA-SP-13-001E},
