Report Number: R16E0019 Responsible Representative: Yuichi Matsuo(Aeronautical Technology Directorate, Numerical Simulation Research Unit) Contact Information: Atsushi Hashimoto(hashimoto.atsushi@jaxa.jp) Members: Atsushi Hashimoto, Syuusaku Takeda, Takashi Ishida Subject Category: Aviation(Aircraft) Abstract Transonic buffet is characterized by unsteady shock excursions. In the numerical prediction of transonic buffet boundary, URANS have used. This research, we introduced numerical perturbation method into FaSTAR to improve accuracy of the prediction. As a result, we found that this method could produce the transonic buffet more precisely. Goal We develop・・・<<read more>>
Report Number: R16E0018 Responsible Representative: Yuichi Matsuo(Aeronautical Technology Directorate, Numerical Simulation Research Unit) Contact Information: Keiichi Kitamura(kitamura@ynu.ac.jp) Members: Takuya Aogaki, Atsushi Hashimoto, Keiichi Kitamura, Kanta Fukumoto, Koki Takabayashi, Toshimasa Takahama, Ayano Inatomi, Ryusuke Yamagata, Toshiaki Harada Subject Category: Basic Research(CFD) Abstract New, high resolution schemes 'Post Limiter' and 'HR-SLAU2'(numerical flux) have been incorporated into the numerical analysis code 'FaSTAR'. The enhanced 'FaSTAR' actually attained higher resolution than the original version, and its normal operation on JSS2 was confirmed. We therefore・・・<<read more>>
