First, a numerical simulation was performed for a turbulent flow in an idealized urban canyon with the homogeneous laminar flow at the inlet boundary, and it was found that a large-scale turbulent structure was generated within the urban canopy. Second, the results of the different wind-direction fluctuations show that effects of them on large-scale turbulent structures and gas dispersion within the canopy are quite small. Large-scale turbulent structures within the canopy are mainly generated by block.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C); 研究期間：2018～2021; 課題番号：18K04471; 研究分野：都市環境; 科研費の分化・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ(WEKO2)","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Michioka, Takenobu"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"道岡, 武信"},{"creatorName":"ミチオカ, タケノブ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"33464","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"20371370","nameIdentifierScheme":"NRID","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/search/?kw=20371370"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-12-05"}],"displaytype":"detail","filename":"18K04471seika.pdf","filesize":[{"value":"645.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"18K04471seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/23366/files/18K04471seika.pdf"},"version_id":"cdcfeb1d-5fc1-4a2f-bb52-c6e1350f7df5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"都市街区","subitem_subject_scheme":"Other"},{"subitem_subject":"乱流","subitem_subject_scheme":"Other"},{"subitem_subject":"ガス拡散","subitem_subject_scheme":"Other"},{"subitem_subject":"数値シミュレーション","subitem_subject_scheme":"Other"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"都市街区内の風の揺らぎのメカニズムとガス拡散挙動の解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"都市街区内の風の揺らぎのメカニズムとガス拡散挙動の解明","subitem_title_language":"ja"},{"subitem_title":"Investigation of mechanism of wind speed fluctuation and gas dispersion within urban canopy","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4819"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-12-05"},"publish_date":"2022-12-05","publish_status":"0","recid":"23366","relation_version_is_last":true,"title":["都市街区内の風の揺らぎのメカニズムとガス拡散挙動の解明"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-09-12T05:10:11.843234+00:00"}
