| Outline of Final Research Achievements |
To contribute to the further improvement of safety, fuel consumption and environmental compatibility of an aircraft, as a baseline technology, a hierarchical Cartesian grid method applicable to the analysis of high Reynolds number compressible flow which is important in the aerospace field is developed. It was possible to carry out analysis of the flow field around an aircraft until now, but there were various problems in the analysis using the hierarchical Cartesian grid method which is capable of fully automatic grid generation. In this study, we have tackled those issues and have shown the effectiveness of the new proposed method through various analysis cases. It is shown that the newly constructed fluid analysis method can be applied to aerodynamics and aeroacoustic analysis, fluid structure interaction problem and optimization calculation around wings and aircraft.
