Three type models of Savonius rotor are constructed and tested in a water tunnel to improve and clarify the power performance. Flow field around the rotor is examined visually to reveal the enhancement mechanisms of power coefficient using the double-step rotor. Flow visualization showed the difference of flow patterns at the central section between the standard (single-step) rotor and the double-step one. A meandering flow in the axial direction of the rotor was observed only for the double-step rotor. This flow had the pressure restoration effect at the returning blade's concave side and the torque strengthened effect at the advancing blade's convex side. As a consequence, the power coefficient was 10% improved.","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Journal of Fluid Science and Technology. 3(3):410-419 (2008)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"Iio, S","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.HecNbpkh.html"},{"subitem_link_text":"Ikeda, T","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.OCfhZhkh.html"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本機械学会"}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1299/jfst.3.410"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1299/jfst.3.410","subitem_relation_type_select":"DOI"}}]},"item_6_rights_62":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 2008 社団法人日本機械学会"}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1880-5558","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nakajima,  M"}],"nameIdentifiers":[{"nameIdentifier":"38452","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iio,  S"}],"nameIdentifiers":[{"nameIdentifier":"38453","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ikeda,  T"}],"nameIdentifiers":[{"nameIdentifier":"38454","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":"2015-09-28"}],"displaytype":"detail","filename":"Performance_of_Double-step_Savonius_Rotor_for_Environmentally_Friendly_Hydraulic_Turbine.pdf","filesize":[{"value":"3.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Performance_of_Double-step_Savonius_Rotor_for_Environmentally_Friendly_Hydraulic_Turbine.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/12575/files/Performance_of_Double-step_Savonius_Rotor_for_Environmentally_Friendly_Hydraulic_Turbine.pdf"},"version_id":"c371ddf4-1b03-4727-a1c3-8dc9e3da8215"}]},"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 Double-step Savonius Rotor for Environmentally Friendly Hydraulic Turbine","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Performance of Double-step Savonius Rotor for Environmentally Friendly Hydraulic Turbine","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["1222"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-06-09"},"publish_date":"2009-06-09","publish_status":"0","recid":"12575","relation_version_is_last":true,"title":["Performance of Double-step Savonius Rotor for Environmentally Friendly Hydraulic Turbine"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:02:01.654108+00:00"}
