A grid system around an automobile has a multi-grid structure and is generated by a trans-finite-inter-polation method. The number of grid points is 112 by 73 by 56 and the Reynolds number based on the length of the automobile is 5,000,000. The calculation of a flow field is done on Fujitsu VP200 and its computational time is about 20 hours. Computed flow fields of 200 time steps are stored in magnetic tapes. Using them, streak-lines are calculated on a mini-supercomputer C-1 and even then visualized on a graphic workstation IRIS 4D. A motion film is taken the screen of IRIS 4D frame by flame using a computer-controlled VTR system. A longitudinal vortex on the side-window is almost steady. However, the other vortices, such as a horse-shoe vortex in front of the front windshield and vortices on the rear-window, show periodical changes and are shed one by one. It is found that a motion film makes the unsteady three-dimensional flow understandable and inevitable. Also, the amount of the data of the three-dimensional unsteady calculation is so huge that adequate shortening of data is necessary.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALSP0009010","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL SP-9","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-260X","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"日産自動車開発システム部"},{"subitem_text_value":"日産自動車中央研究所車両研究所"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Nissan Motor Co., Ltd."},{"subitem_text_language":"en","subitem_text_value":"Nissan Motor Co., Ltd."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"藤谷, 克郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"姫野, 龍太郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujitani, Katsuro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Himeno, Ryutaro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-28"}],"displaytype":"detail","filename":"nalsp0009010.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0009010.pdf","url":"https://jaxa.repo.nii.ac.jp/record/43301/files/nalsp0009010.pdf"},"version_id":"4259a045-f36a-42fc-90f6-e48a40dd634b"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"計算による3次元非定常流れの可視化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"計算による3次元非定常流れの可視化"}]},"item_type_id":"3","owner":"1","path":["1893","1915"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"43301","relation_version_is_last":true,"title":["計算による3次元非定常流れの可視化"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:17:54.767546+00:00"}
