The swimming efficiency of the fish model under parallel swimming was obtained from the calculated surrounding fluid force and compared for different neighboring distances. The flow field around the fish model was also examined. The swimming efficiency of two fish models swimming parallelly was improved by  approximately 10% when they were separated by a distance of 0.4L, where L is the total length of the model. In addition, the flow field behind the fish body was examined under both inphase and antiphase conditions and at inter-individual distances of 0.8L and 1.2L. The apparent flow speed in the distance range of 0.5-2.0L from the  midpoint of the snouts of the two individuals was lower than the swimming speed.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"研究分野：水産学・漁業学","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_30001_file22":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"20K04355seika.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://kindai.repo.nii.ac.jp/record/2000376/files/20K04355seika.pdf"},"version_id":"e7aac07b-023b-4657-9c21-cb40b1519a2b"}]},"item_30001_funding_reference15":{"attribute_name":"助成情報","attribute_value_mlt":[{"subitem_award_numbers":{"subitem_award_number":"20K04355","subitem_award_uri":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-20K04355/"},"subitem_award_titles":[{"subitem_award_title":"魚群行動の流体力学的機能性の解明","subitem_award_title_language":"ja"},{"subitem_award_title":"Swimming efficiency and flow field around fish in school","subitem_award_title_language":"en"}],"subitem_funder_names":[{"subitem_funder_name":"独立行政法人日本学術振興会","subitem_funder_name_language":"ja"},{"subitem_funder_name":"Japan Society for the Promotion of Science","subitem_funder_name_language":"en"}]}]},"item_30001_language10":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_30001_subject7":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"バイオメカニクス","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"魚群行動","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"PTV(流体可視化計測)解析","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"CFD(数値流体力学)解析","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"エネルギーコスト","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_30001_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"魚群行動の流体力学的機能性の解明","subitem_title_language":"ja"},{"subitem_title":"Swimming efficiency and flow field around fish in school","subitem_title_language":"en"}]},"item_30001_version_type12":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_title":"魚群行動の流体力学的機能性の解明","item_type_id":"40001","owner":"42","path":["1697004343623"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-11-08"},"publish_date":"2023-11-08","publish_status":"0","recid":"2000376","relation_version_is_last":true,"title":["魚群行動の流体力学的機能性の解明"],"weko_creator_id":"42","weko_shared_id":-1},"updated":"2024-10-23T00:48:16.337402+00:00"}
