JAXA Supercomputer System Annual Report April 2017-March 2018 Report Number: R17EACA16 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Naofumi Ohnishi, Tohoku University Contact Information: Naofumi Ohnishi ohnishi@rhd.mech.tohoku.ac.jp Members: Naofumi Ohnishi, Shintaro Sato Abstract Dielectric-Barrier-Discharge Plasma Actuators (DBD-PAs) are novel active-flow-control devices using electrohydrodynamic force caused by atmospheric discharge. However, the practical application of the DBD-PA is still challenging due to the low induced flow-velocity. In order to improve the DBD-PA performance, clarification of the discharge process is a key・・・<<read more>>

JAXA Supercomputer System Annual Report April 2017-March 2018 Report Number: R17EACA27 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Junko Kominami, Tokyo Institute of Technology Contact Information: Junko Kominami kominami@mail.jmlab.jp Members: Junko Kominami Abstract When the Sun was formed, protoplanatary disk was formed. It is widely accepted that planets are formed through the coagulation of dust component in the protoplanetary disk. However, the Jovian planets and icy planets were formed can not be explained using classical planet formation. For example,・・・<<read more>>
