Results obtained from the experiment are as follows :When the upper disk approaches the lower one, viscoelasticity of the fluid decreases the pressure below the pressure of corresponding Newtonian fluids, whereas in the case of separating the upper disk from the lower one, the pressure takes minus values of about - 3.5 × 10^5Pa and the magnitude is increased by the viscoelasticity of the fluid used. This minus pressure is raised to a vacuum pressure by the cavitation inception inferred, the vacuum pressure holds constant for a duration and finally the pressure abruptly increases by the cavity extinction which accompanies pressure vibrations of high frequencies. These experimental results are qualitatively explained using the assumption of squeezing flow and the constitutive equation of the second order fluid.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"45058","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hasegawa, Tomiichi"}]},{"nameIdentifiers":[{"nameIdentifier":"45059","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sorimachi, Kazunori"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本機械学会"}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002388489","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本機械学会"},{"subitem_rights":"本文データは学会の許諾に基づくCiNiiからの複製である"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00187441","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03875016","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"長谷川, 富市"}],"nameIdentifiers":[{"nameIdentifier":"45056","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"反町, 和則"}],"nameIdentifiers":[{"nameIdentifier":"45057","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":"2019-07-30"}],"displaytype":"detail","filename":"9_0030.pdf","filesize":[{"value":"391.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"9_0030.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/3740/files/9_0030.pdf"},"version_id":"83a38eac-8d44-40ec-a99d-c9fbc823fb9a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Viscoelastic Fluid","subitem_subject_scheme":"Other"},{"subitem_subject":"Cavitation","subitem_subject_scheme":"Other"},{"subitem_subject":"Unsteady Flow","subitem_subject_scheme":"Other"},{"subitem_subject":"Squeezing Flow","subitem_subject_scheme":"Other"},{"subitem_subject":"Reverse Squeezing Flow","subitem_subject_scheme":"Other"},{"subitem_subject":"Dilute Polymer Solution","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"液体中で接近し離反する平行2円板間の圧力に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"液体中で接近し離反する平行2円板間の圧力に関する研究"},{"subitem_title":"液体中で接近し離反する平行2円板間の圧力に関する研究","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-04-08"},"publish_date":"2008-04-08","publish_status":"0","recid":"3740","relation_version_is_last":true,"title":["液体中で接近し離反する平行2円板間の圧力に関する研究"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:50.140630+00:00"}
