And the model-net was made according\nto the full-scale one, in which the length of the rope was made to be a fraction of the\noriginal one, while the angle to the water-bottom was kept equal to that of the actual case.\n(2) It was ascertained that the force acting on the fixed-net was to be adequately\nexpressed in the following equation,","subitem_description_type":"Other"},{"subitem_description":"R=Cρ/2S_0(1-kV)V^2","subitem_description_type":"Other"},{"subitem_description":"Here, k is the coefficient of the net-deformation, and C is the coefficient of the\ndrag influenced by the factors except the deformation. Therefore in any fixed-net, the\napproximate value of the drag at any current velocity came to be easily computed.\nWhile the current-velocity is lower than 18 cm/sec, the value of k is 0.025~0.045,\nand that of C is approximately 6.3×10^{-4}.\n(3) (a) As to the net whose net-foot detatches itself from the water bottom, the\nhydrodynamic force on the net and its direction were counted. It was ascertained that\nthe vertical component of it is the lift acting on the net, and that the horizontal component of it is the drag on the net, and this is equal to the horizontal component of the\nforce on the rope.\n(b) In the one whose net-foot attatches itself to the water-bottom, it was ascertained\nthat besides the force acting on the sand-bag rope, there is another force on the net-foot,\nand that this works as a kind of downward force. These are the phenomena which have\nbeen left unobserved hitherto.","subitem_description_type":"Other"}]},"item_7_full_name_3":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"金森, 政治"}]}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0453087X","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040498","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"660","subitem_subject_scheme":"NDC"}]},"item_7_text_24":{"attribute_name":"公開者よみ","attribute_value_mlt":[{"subitem_text_value":"カゴシマ ダイガク"}]},"item_7_text_25":{"attribute_name":"公開者別名","attribute_value_mlt":[{"subitem_text_value":"Kagoshima University"}]},"item_7_version_type_14":{"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":"KANAMORI, Masaji"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-31"}],"displaytype":"detail","filename":"AN00040498_v8_p145-180.pdf","filesize":[{"value":"22.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00040498_v8_p145-180.pdf","url":"https://ir.kagoshima-u.ac.jp/record/10899/files/AN00040498_v8_p145-180.pdf"},"version_id":"e9a9bebf-9a31-477f-8b14-288683f27af7"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"On the Physical Analysis of the Fixed-fishing-net Resistance","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"On the Physical Analysis of the Fixed-fishing-net Resistance"}]},"item_type_id":"7","owner":"3","path":["40","4849"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-08"},"publish_date":"2012-05-08","publish_status":"0","recid":"10899","relation_version_is_last":true,"title":["On the Physical Analysis of the Fixed-fishing-net Resistance"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2024-01-30T05:51:42.157219+00:00"}
