However, below ns = 60, the pump efficiency is not yet clear, and the spiral angle of a volute casing becomes too small to manufacture. To solve this problem, a circular casing is considered appropriate in the very low ns range. The present study is aimed to reveal the relation between pump efficiency and a specific speed in the range of ns ≦ 60, when a circular casing is used. The results show that a circular casing gives higher efficiency than a spiral casing, and that radial thrust is considerably small in both casings compared with that of ordinary specific speed pump.","subitem_description_type":"Abstract"}]},"item_2_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_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{},{}],"names":[{}]}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan Society of Mechanical Engineers"}]},"item_2_relation_44":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.jstage.jst.go.jp/article/jfst/2/1/130/_pdf/-char/ja/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jstage.jst.go.jp/article/jfst/2/1/130/_pdf/-char/ja/","subitem_relation_type_select":"URI"}}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18805558","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Engineering, Yokohama National University, 79-5 Tokiwadai, Hodogaya-ku, Yokohama-shi, Kanagawa, 240-8501 Japan"},{"subitem_text_value":"Faculty of Engineering, Yokohama National University, 79-5 Tokiwadai, Hodogaya-ku, Yokohama-shi, Kanagawa, 240-8501Japan"},{"subitem_text_value":"Faculty of Engineering, Yokohama National University, 79-5 Tokiwadai, Hodogaya-ku, Yokohama-shi, Kanagawa, 240-8501Japan"},{"subitem_text_value":"Industry-Academic Cooperation Foundation, Korea Maritime University, 1, Dongsam-Dong, Youngdo-ku, Busan, 606-791 Korea"}]},"item_2_version_type_18":{"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":"Kagawa, Shusaku"}],"nameIdentifiers":[{"nameIdentifier":"16538","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":"16540","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Choi, Young-do"}],"nameIdentifiers":[{"nameIdentifier":"16541","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-156.pdf","filesize":[{"value":"4.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"B-156.pdf","url":"https://ynu.repo.nii.ac.jp/record/3797/files/B-156.pdf"},"version_id":"a6b91f61-c731-4f31-96cf-9052d092300d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Turbomacbinary","subitem_subject_scheme":"Other"},{"subitem_subject":"Fluid Machinery","subitem_subject_scheme":"Other"},{"subitem_subject":"Pump","subitem_subject_scheme":"Other"},{"subitem_subject":"Very Low Specific Speed","subitem_subject_scheme":"Other"},{"subitem_subject":"Matching Performance","subitem_subject_scheme":"Other"},{"subitem_subject":"Circular Casing","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Performance of Very Low Specific Speed Centrifugal Pumps with Circular Casing","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Performance of Very Low Specific Speed Centrifugal Pumps with Circular Casing"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-09-17"},"publish_date":"2008-09-17","publish_status":"0","recid":"3797","relation_version_is_last":true,"title":["Performance of Very Low Specific Speed Centrifugal Pumps with Circular Casing"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T21:40:13.824065+00:00"}
