Three simple modifications are considered: the Reynolds-averaged Navier-- Stokes (RANS) turbulence model coefficient, Crot, is calibrated to achieve a better leading-edge separation pre-diction in DDES; the large-eddy simulation (LES) coefficient, CDES, is assessed to obtain better dissipation control in DDES; and dirty-cell treatments in three-dimensional unstructured grids are conducted for a smooth LES/ RANS transition. Numerical results confirm the effects of the three aforementioned steps, such as the repro-ducibility of the measured pressure distribution over the main wing in unsteady turbulence simulations of low -speed buffet around the NASA Common Research Model. Thus, these modifications will potentially serve as good alternatives, without major programming efforts, to the conventional approaches for practitioners.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Pergamon-Elsevier Science Ltd","subitem_publisher_language":"en"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.compfluid.2023.105814","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00457930","subitem_source_identifier_type":"PISSN"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Kitamura, K.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"0000-0001-7550-8990","nameIdentifierScheme":"ORCID","nameIdentifierURI":"https://orcid.org/0000-0001-7550-8990"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Takagi, Y.","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Harada, T.","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Yasumura, Y.","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Japan Aerospace Exploration Agency (JAXA)","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Kanamori, M.","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Japan Aerospace Exploration Agency (JAXA)","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Hashimoto, A.","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","displaytype":"detail","fileDate":[{"fileDateType":"Issued","fileDateValue":"2023-02-17"}],"filename":"1-s2.0-S0045793023000397-main.pdf","filesize":[{"value":"3.5 MB"}],"format":"application/pdf","licensetype":"license_5","mimetype":"application/pdf","url":{"label":"1-s2.0-S0045793023000397-main.pdf","objectType":"fulltext","url":"https://ynu.repo.nii.ac.jp/record/12302/files/1-s2.0-S0045793023000397-main.pdf"},"version_id":"01a3cd2a-88b2-44d7-ade7-f7252d52df3e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"DDES; RANS; Spalart-Allmaras; HR-SLAU2; Buffet; Leading-Edge Separation","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Leading-Edge separation behaviors in SA RANS and SA-based DDES: Simple modifications for improved prediction","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Leading-Edge separation behaviors in SA RANS and SA-based DDES: Simple modifications for improved prediction","subitem_title_language":"en"}]},"item_type_id":"2","owner":"17","path":["496"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-02-07"},"publish_date":"2023-02-07","publish_status":"0","recid":"12302","relation_version_is_last":true,"title":["Leading-Edge separation behaviors in SA RANS and SA-based DDES: Simple modifications for improved prediction"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2024-07-31T04:46:13.237100+00:00"}
