In experimentally, a design Mach number of 1.5 followed by a cylindrical duct with an inner diameter of 10 mm, and length of 50 mm are considered to measure the density, internal flow features of jet combing with the computed tomography. In theoretically, a modified vortex sheet model taking viscosity into account has been proposed. The properties of Bessel’s and Mathieu functions with the first Fourier mode of eigenvalues are executed for the individual exit geometry to evaluate the explicit solution of inviscid and viscous jet separately. The embodied results of density, shock-cell spacing, and size measuring have also been examined theoretically. In comparison, the accomplished yields are shown better agreement with published data due to the aspect ratios, nozzle pressure ratios and design Mach number arbitrarily.","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第202号"}]},"item_10006_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"1246","nameIdentifierScheme":"WEKO"}],"names":[{"name":"イスラム ムハマド ミナルル"}]}]},"item_10006_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":[{"creatorNames":[{"creatorName":"Islam Muhammad, Minarul","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1245","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-12-20"}],"displaytype":"detail","filename":"(KKDE1202IM)甲第202号_イスラム　ムハマド　ミナルル.pdf","filesize":[{"value":"5.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"(KKDE1202IM)甲第202号_イスラム　ムハマド　ミナルル","objectType":"fulltext","url":"https://kitakyu.repo.nii.ac.jp/record/1044/files/(KKDE1202IM)甲第202号_イスラム　ムハマド　ミナルル.pdf"},"version_id":"e92deed4-6dd6-471c-980d-ab63013a81f8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Supersonic Jet","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Shock Wave","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Shock-cell Spacing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Rainbow Schlieren Deflectometry","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Linearized Model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Bessel’s Function","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mathieu Function","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Aspect Ratio","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Nozzle Pressure Ratio","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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Analytical Investigation on the Underexpanded Jet Issuing from Circular and Elliptic Nozzles","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Analytical Investigation on the Underexpanded Jet Issuing from Circular and Elliptic Nozzles","subitem_title_language":"en"}]},"item_type_id":"10006","owner":"14","path":["10"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-12-20"},"publish_date":"2022-12-20","publish_status":"0","recid":"1044","relation_version_is_last":true,"title":["Analytical Investigation on the Underexpanded Jet Issuing from Circular and Elliptic Nozzles"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-04-20T06:08:06.826057+00:00"}
