The first normal stress difference in a shear flow was measured by utilizing reactions exerted by a jet issuing from a capillary, and the elongational stresses were also obtained separately with reactions or pressure drops produced in the flow through small orifices. The following points were clarified: the first normal stress difference τ_\u003c11\u003e-τ_\u003c22\u003e had a relationship of the power law type with the shear rate γ, that is, τ_\u003c11\u003e-τ_\u003c22\u003e∝γ. For the PEO 5 ppm solution, the power law index s was 2.0, as predicted with the Maxwell model, and in this case, the relaxation time was determined as 0.0016 second. For the other solutions used, we had 1.2\u003c s \u003c 2.0 and the measured first normal stress differences could be expressed with a modified Maxwell model. The elongational stresses measured with the two methods of jet reaction and pressure drop generally agree with each other. The elongational stress can be expressed, albeit approximately, with the Maxwell model or the modified Maxwell model depending on the concentration of the solution used. In some cases, the elongational stresses of PEO solutions, at least qualitatively, agree with predicted values of the yo-yo model proposed by Ryskin.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "45079", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Hasegawa, Tomiichi"}]}, {"nameIdentifiers": [{"nameIdentifier": "45080", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Saitoh, Hidetoshi"}]}, {"nameIdentifiers": [{"nameIdentifier": "45081", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ishizuka, Kazuo"}]}, {"nameIdentifiers": [{"nameIdentifier": "45082", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Nakamura, Hitoshi"}]}, {"nameIdentifiers": [{"nameIdentifier": "45083", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Narumi, Takatsune"}]}]}, "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/110002402107", "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": "45074", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "斎藤, 秀俊"}], "nameIdentifiers": [{"nameIdentifier": "45075", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "石塚, 一男"}], "nameIdentifiers": [{"nameIdentifier": "45076", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "中村, 仁志"}], "nameIdentifiers": [{"nameIdentifier": "45077", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "鳴海, 敬倫"}], "nameIdentifiers": [{"nameIdentifier": "45078", "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", "download_preview_message": "", "file_order": 0, "filename": "9_0027.pdf", "filesize": [{"value": "509.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 509400.0, "url": {"label": "9_0027.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/3743/files/9_0027.pdf"}, "version_id": "de7f13b2-ef4f-4732-97bc-35dc6d56f5dd"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Shear Flow", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Viscoelastic Fluid", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Non-Newtonian Fluid", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Elongational Flow", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Elongational Viscosity", "subitem_subject_scheme": "Other"}, {"subitem_subject": "First Normal Stress Difference", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Dilute Polymer Solution", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Maxwell Model", "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": "せん断流と伸張流における非常に希薄な高分子溶液の弾性の測定", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "せん断流と伸張流における非常に希薄な高分子溶液の弾性の測定"}, {"subitem_title": "せん断流と伸張流における非常に希薄な高分子溶液の弾性の測定", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/5729", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-04-08"}, "publish_date": "2008-04-08", "publish_status": "0", "recid": "3743", "relation": {}, "relation_version_is_last": true, "title": ["せん断流と伸張流における非常に希薄な高分子溶液の弾性の測定"], "weko_shared_id": null}
