To address this limitation within a second-order framework, a novel strategy for hybridizing MUSCL with the tangent of the hyperbola interface capturing technique for both steady and unsteady compressible flows is presented. This hybridization optimizes the process based on the degree of nonlinearity and discontinuity around the target cells, providing a novel method to sharply resolve weak shock waves and robustly compute strong shock waves within the hybrid scheme. The proposed scheme sharply captures exceedingly weak shock waves that conventional MUSCL fails to resolve accurately due to excessive numerical dissipation. Furthermore, for resolving small vortices induced by instability at slip lines, computational results demonstrate high-resolution surpassing fifth-order spatial accuracy schemes within this second-order spatial accuracy framework with less computational cost. Moreover, the scheme exhibits commendable convergence and robustness when applied to steady-state problems featuring strong shock waves. This scheme offers a more precise and high-resolution alternative to conventional MUSCL for compressible flow computations, as it requires no additional stencil for reconstruction, unlike conventional fifth-order schemes.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Institute of Physics","subitem_publisher_language":"en"}]},"item_2_relation_13":{"attribute_name":"item_2_relation_13","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1063/5.0198163","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_11":{"attribute_name":"item_2_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AA10986202","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"item_2_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"10897666","subitem_source_identifier_type":"EISSN"}]},"item_2_version_type_18":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Faculty of Engineering, Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Fukushima, Gaku","creatorNameLang":"en"},{"creatorName":"福嶋, 岳","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"0000-0003-2743-3140","nameIdentifierScheme":"ORCID","nameIdentifierURI":"https://orcid.org/0000-0003-2743-3140"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Faculty of Engineering, Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Kitamura, Keiichi","creatorNameLang":"en"},{"creatorName":"北村, 圭一","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"0000-0001-7550-8990","nameIdentifierScheme":"ORCID","nameIdentifierURI":"https://orcid.org/0000-0001-7550-8990"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-05-20"}],"displaytype":"detail","fileDate":[{"fileDateType":"Issued","fileDateValue":"2024-04-10"}],"filename":"046110_1_5.0198163.pdf","filesize":[{"value":"9.2 MB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://ynu.repo.nii.ac.jp/record/2000921/files/046110_1_5.0198163.pdf"},"version_id":"ec924ca8-02f1-4208-87c2-f32f0d62cc99"},{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-15"}],"fileDate":[{"fileDateType":"Issued","fileDateValue":"2024-04-10"}],"filename":"Figure.ppt","filesize":[{"value":"549 KB"}],"format":"application/vnd.ms-powerpoint","mimetype":"application/vnd.ms-powerpoint","url":{"objectType":"dataset","url":"https://ynu.repo.nii.ac.jp/record/2000921/files/Figure.ppt"},"version_id":"d793c75b-663a-4eea-b401-c3053b8fcb3e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Numerical methods, Finite volume methods, Computational fluid dynamics, Fluid dynamics, Compressible flows, Shock waves","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":"item_resource_type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Improved hybrid approach of monotonic upstream-centered scheme for conservation laws and discontinuity sharpening technique for steady and unsteady flows","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Improved hybrid approach of monotonic upstream-centered scheme for conservation laws and discontinuity sharpening technique for steady and unsteady flows","subitem_title_language":"en"}]},"item_type_id":"2","owner":"17","path":["496"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-05-20"},"publish_date":"2024-05-20","publish_status":"0","recid":"2000921","relation_version_is_last":true,"title":["Improved hybrid approach of monotonic upstream-centered scheme for conservation laws and discontinuity sharpening technique for steady and unsteady flows"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2024-10-15T08:05:44.864678+00:00"}
