JAXA Supercomputer System Annual Report April 2017-March 2018 Report Number: R17ETET18 Subject Category: Skills Acquisition System PDF Responsible Representative: Takashi Yamane, Aeronautical Technology Directorate, Propulsion Research Unit Contact Information: Seiji Yoshida yoshida.seiji@jaxa.jp Members: YOSHIDA Seiji(JAXA), Mitsumasa Makida(JAXA), Naoki Nakamura(ASIRI), Takeishi Ikumi(Waseda univ.) Abstract Lean combustion is promising to reduce nitrogen oxide emission from jet-engines. To solve combustion instability, that is a problem of lean combustion, a pilot burner for ensuring stable combustion and a main burner for performing lean, low-NOx・・・<<read more>>
JAXA Supercomputer System Annual Report April 2017-March 2018 Report Number: R17ETET21 Subject Category: Skills Acquisition System PDF Responsible Representative: Takashi Aoyama, Aeronautical Technology Directorate, Numerical Simulation Research Unit Contact Information: Atsushi Hashimoto hashimoto.atsushi@jaxa.jp Members: Yoimi Kojima, Yoichi Saito Abstract Shock-wave/boundary layer interaction on the suction side of the wing at high Mach number and/or high angle of attack leads to large scale self-sustained motion of the shock wave. This phenomenon is called transonic buffet. The buffet leads to dangerous structural・・・<<read more>>
