The purpose of the \npresent study is to understand this puzzling motion. First, we observed a trajectory of a \nfalling wetted circular cylinder suspended with a thread, from which the aerodynamic \nforce coefficients were estimated. Using these values, trajectories of the flying dry and \nwetted soft tennis ball were simulated by a finite difference method. It was found that the \nwetted ball with topspin does not bend upward, but travels in a significantly flatter \ntrajectory.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学工学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Faculty of Engineering, University of Miyazaki","subitem_publisher_language":"en"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00732558","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05404924","subitem_source_identifier_type":"ISSN"}]},"item_10002_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":"小園, 茂平","creatorNameLang":"ja"},{"creatorName":"オゾノ, シゲヒラ","creatorNameLang":"ja-Kana"},{"creatorName":"Ozono, Shigehira","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"出口, 新"},{"creatorName":"デグチ, アラタ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Deguchi, Arata","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-06-21"}],"displaytype":"detail","filename":"KJ00004439481.pdf","filesize":[{"value":"537.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004439481.pdf","url":"https://miyazaki-u.repo.nii.ac.jp/record/2437/files/KJ00004439481.pdf"},"version_id":"4ac6d668-8c5a-4d8d-9550-fd50e49018da"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Aerodynamics force, Reynolds number, Soft tennis ball, Spin parameter, Wetted surface","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"濡れた表面をもつソフトテニスボールの飛翔特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"濡れた表面をもつソフトテニスボールの飛翔特性","subitem_title_language":"ja"},{"subitem_title":"Aerodynamic Characteristics of a Flying Soft Tennis Ball","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"5","path":["73","36","330","316"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-06-28"},"publish_date":"2007-06-28","publish_status":"0","recid":"2437","relation_version_is_last":true,"title":["濡れた表面をもつソフトテニスボールの飛翔特性"],"weko_creator_id":"5","weko_shared_id":2},"updated":"2023-07-29T23:31:13.323015+00:00"}
