In this study, a very simple device of using shallow grooves mounted on a casing wall, known as \"J-Groove\", is proposed and studied experimentally and theoretically. The result shows that 70% of axial thrust in an industry, 4-stage centrifugal pump can be reduced at the best efficiency point. Moreover, the analytical method of \"interfered gap flow\" is established and a simple formula which can determine the optimum dimension of groove and its location is proposed.","subitem_description_type":"Abstract"}]},"item_3_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{},{}],"names":[{"name":"クロカワ, ジュンイチ"}]}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"181","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40017976","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=40017976"}],"names":[{"name":"黒川, 淳一"}]}]},"item_3_publisher_37":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"International Association of Hydraulic Research (IAHR)"}]},"item_3_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Yokohama National Univ., Japan"},{"subitem_text_value":"Tatsuno Corporetion, Japan"},{"subitem_text_value":"Yokohama National Univ., Japan"},{"subitem_text_value":"Yokohama National Univ., Japan"},{"subitem_text_value":"Yokohama National Univ., Japan"}]},"item_3_version_type_20":{"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":"Abe, Heishiro"}],"nameIdentifiers":[{"nameIdentifier":"16460","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsumoto, Kazunari"}],"nameIdentifiers":[{"nameIdentifier":"16461","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kurokawa, Junichi"}],"nameIdentifiers":[{"nameIdentifier":"181","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40017976","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=40017976"}]},{"creatorNames":[{"creatorName":"Matsui, Jun"}],"nameIdentifiers":[{"nameIdentifier":"16463","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Choi, Young-Do"}],"nameIdentifiers":[{"nameIdentifier":"16464","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":"2016-09-16"}],"displaytype":"detail","filename":"B-151.pdf","filesize":[{"value":"684.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"B-151.pdf","url":"https://ynu.repo.nii.ac.jp/record/3787/files/B-151.pdf"},"version_id":"baa928fe-3785-424c-9c82-8ae8f7ddd062"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Centrifugal Pump","subitem_subject_scheme":"Other"},{"subitem_subject":"Axial Thrust","subitem_subject_scheme":"Other"},{"subitem_subject":"J-Groove","subitem_subject_scheme":"Other"},{"subitem_subject":"Thrust Balancing Device","subitem_subject_scheme":"Other"},{"subitem_subject":"Boundary layer","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Analysis and Control of Axial Thrust in Centrifugal Pump by Use of J-Groove","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Analysis and Control of Axial Thrust in Centrifugal Pump by Use of J-Groove"}]},"item_type_id":"3","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-09-17"},"publish_date":"2008-09-17","publish_status":"0","recid":"3787","relation_version_is_last":true,"title":["Analysis and Control of Axial Thrust in Centrifugal Pump by Use of J-Groove"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T21:40:31.318327+00:00"}
