The system produces compressed air instead of electricity. This is because it is not desirable to convert wave energy directly into electric power in large amounts due to both low energy conversion efficiency and the consequent irregularity of the electric output. Compressed air is easy to store and safe to use in coastal areas. The objective of this study is to understand how much energy from the incoming waves can be captured for use by the system. Laboratory experiments were carried out to determine the effects of wave and system load conditions on energy conversion efficiency and hydrodynamic characteristics for the system. The test results show that the system can operate with a high degree of efficiency under loops of the standing wave formed in front of a structure. A reduction of wave reflection can be achieved by the system under a wide range of wave conditions.","subitem_description_type":"Abstract"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会 = Japan Society of Civil Engineers"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2208/jscejoe.68.I_911","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/browse/jscejoe/-char/ja/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jsce.or.jp/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © Japan Society of Civil Engineers 土木学会"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2185-4688","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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":"楳田, 真也"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"大貝, 秀司"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"石田, 啓"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"TE-PR-UMEDA-S-911.pdf","filesize":[{"value":"400.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TE-PR-UMEDA-S-911.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/9956/files/TE-PR-UMEDA-S-911.pdf"},"version_id":"1eab56bb-5d44-4293-9797-9fea4cf8ebea"}]},"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":"浮体式波エネルギー吸収装置による圧縮空気生産に関する実験的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"浮体式波エネルギー吸収装置による圧縮空気生産に関する実験的研究"},{"subitem_title":"Compressed air generation using a floating wave energy converter","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["936"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"9956","relation_version_is_last":true,"title":["浮体式波エネルギー吸収装置による圧縮空気生産に関する実験的研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:46:09.641254+00:00"}
