Former part of this article shows the background why and how this center was newly established in JAXA. First key issue here is that CFD activities in JAXA have been focused on high-speed flow simulations mostly for aircraft but space development requires flow simulations in other areas too. Second key issue is that CFD in space development has been used mostly when problems occur in the development process but such is only a small portion of CFD capability. We believe that CFD can do much more especially if CFD is used in the preliminary and main design process. JEDI center focuses on the CFD tools in such design stages in addition to the activity making CFD more useful in solving the problems in the development process. Latter part of this article shows the background CFD technology. Two examples are shown. First is how to reduce the computational cost with keeping sufficient accuracy for flow simulations. Second is how to enable CFD being useful in the preliminary design stage. These will become key CFD technologies in the JEDI activity.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
