The velocity along the center line near the orifices was measured with a laser doppler anemometer, stream lines in the whole flow region were photographed, and the following points were clarified : (1) The center line velocities of liquid paraffin agree with the theoretical value of Stokes flow in the region of Reynolds numbers below 10. (2) With distilled water, a diverging angle of the issuing flow from a larger orifice is smaller than that of the issuing flow from a smaller orifice. Furthermore, a characteristic isolated vortex is generated on the downstream side of the orifice at the Reynolds number of from 10 to 30. (3) With ethanol used as a test liquid, the diverging angle of the issuing flow is small even for the Reynolds number of less than 10, and the flow resembles a jet. (4) The magnitude of the diverging angle of the issuing flow have a decisive effect on the value of the excess pressure drop at the same Reynolds number ; the larger the diverging angles is, the smaller the excess pressure drop is. (5) The dimension of the isolated vortex generated with the outlet flow of water is, when non-dimensionalized with the orifice diameter, correlated with a dimensionless number V(λ/ν)^\u003c1/2\u003e, where V is the mean orifice velocity, λ is a time proper to water and ν is the kinematic viscosity.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "45144", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Hasegawa, Tomiichi"}]}, {"nameIdentifiers": [{"nameIdentifier": "45145", "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_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "日本機械学会"}]}, "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": "福冨, 清"}], "nameIdentifiers": [{"nameIdentifier": "45140", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "長谷川, 富市"}], "nameIdentifiers": [{"nameIdentifier": "45141", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "中野, 裕二"}], "nameIdentifiers": [{"nameIdentifier": "45142", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "鳴海, 敬倫"}], "nameIdentifiers": [{"nameIdentifier": "45143", "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": "14_0002.pdf", "filesize": [{"value": "1.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1300000.0, "url": {"label": "14_0002.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/3752/files/14_0002.pdf"}, "version_id": "4ed185a8-9f84-40fb-b56b-104e7a686d17"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Flow through Small Orifices", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Low Reynolds Number", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Velocity Field", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Extensional Flow", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Viscoelastic Fluid", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Relaxation Time", "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": "小孔を通過する流れに関する研究（第2報, 速度場に関する実験）", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "小孔を通過する流れに関する研究（第2報, 速度場に関する実験）"}, {"subitem_title": "小孔を通過する流れに関する研究（第2報, 速度場に関する実験）", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/6303", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-04-23"}, "publish_date": "2008-04-23", "publish_status": "0", "recid": "3752", "relation": {}, "relation_version_is_last": true, "title": ["小孔を通過する流れに関する研究（第2報, 速度場に関する実験）"], "weko_shared_id": null}
