The former half of the present report describes both an outline and the principle of this system for two-dimensional measurements. In the latter half, the L2F-Velocimeter is evaluated by using three types of flows, i.e., two-dimensional wake, three-dimensional boundary layer and quasi two-dimensional free jet with, and occasionally without, seeding particles. Furthermore, several seeding particles such as paraffine vapor, mosquito-repellent smoke and tobacco smoke are used for evaluations. The axial velocity component from the L2F-Velocimeter is pointwisely compared with a calibrated velocity. The comparison is extended to the transverse mean velocity component/fluctuating components with hot-wire measurements, in which great care was taken with the linearity and wire inclination. There is no incongruity in comparison except in low turbulence with less than 2％ intensity to the lal velocity .In summary, features of the fiber optic L2F-Velocimeter are its applicability to natural seed, wall-proximity and non-calibration measurements, although it is apriori known that the L2F-Velocimeter is not adaptable to both reverse flow and high turbulence measurements.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTM0627000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TM-627","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0452-2982","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00314334","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所空力性能部"},{"subitem_text_value":"航空宇宙技術研究所空力性能部"},{"subitem_text_value":"航空宇宙技術研究所空力性能部"},{"subitem_text_value":"航空宇宙技術研究所空力性能部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"高木, 正平"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"室田, 勝一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"桑野, 尚明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"萱場, 重男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKAGI, Shohei","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MUROTA, Katsuichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KUWANO, Naoaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAYABA, Shigeo","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":"2020-01-29"}],"displaytype":"detail","filename":"naltm00627.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltm00627.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44210/files/naltm00627.pdf"},"version_id":"c6d2048a-783c-46c3-9e4b-690004b44699"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"大型低速風洞用ファイバ式三次元レーザ2焦点流速計設備PartIその性能評価:二次元計測を中心として","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"大型低速風洞用ファイバ式三次元レーザ2焦点流速計設備PartIその性能評価:二次元計測を中心として"}]},"item_type_id":"3","owner":"1","path":["1893","1916"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"44210","relation_version_is_last":true,"title":["大型低速風洞用ファイバ式三次元レーザ2焦点流速計設備PartIその性能評価:二次元計測を中心として"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:00:52.896560+00:00"}
