To design the head slider, numerical analysis of the time dependent molecular gas film lubrication equation is indispensable. Recently, the spacing between magnetic head and medium has been reduced to 10 nm. Under such high compression conditions, the convergence of the solution becomes worse.In the present study, we developed a numerical method to integrate the time dependent molecular gas film lubrication equation using an alternated-direction-implicit method, which can give the solution in the accuracy of (Δt)2. Especially, considering the physical characteristics of the flow in the lubrication film, the central finite difference method is applied to the pressure flow term and the upstream finite difference method is applied to the shear flow term and the convergence of the solution is improved.","subitem_description_type":"Other"}]},"item_10_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"23113","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yoshida, Hideyo"}]},{"nameIdentifiers":[{"nameIdentifier":"23114","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"90268326 ","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000090268326 "}],"names":[{"name":"Hayashi, Takefumi"}]}]},"item_10_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"関西大学"}]},"item_10_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10484636","subitem_source_identifier_type":"NCID"}]},"item_10_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1341156X","subitem_source_identifier_type":"ISSN"}]},"item_10_version_type_17":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉田, 英代"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"林, 武文"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-22"}],"displaytype":"detail","filename":"KU-1100-20050715-07.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KU-1100-20050715-07.pdf","url":"https://kansai-u.repo.nii.ac.jp/record/10898/files/KU-1100-20050715-07.pdf"},"version_id":"42dd46f1-12c0-4eba-bff0-4dfa34112bac"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"関西大学","subitem_subject_scheme":"Other"},{"subitem_subject":"Kansai University","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"時間項を含む分子気体潤滑方程式の数値計算法に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"時間項を含む分子気体潤滑方程式の数値計算法に関する研究"}]},"item_type_id":"10","owner":"1","path":["1558"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-06-27"},"publish_date":"2012-06-27","publish_status":"0","recid":"10898","relation_version_is_last":true,"title":["時間項を含む分子気体潤滑方程式の数値計算法に関する研究"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-05-17T02:03:43.138924+00:00"}
