This system uses the massproduced and cheap digital camera and LED(Light Emitting Diode) lamps. The tracer particles, which are lighted by red and green LED flash, are exposed into one picture image, and divided in the post process. There is no inner-clock, so this system can synchronize the rotation of impeller with good accuracy. Also the interval time between red and green flash can be changed freely. Using the blue markings for calibration in the flow area, we can distinguish these markings from particles during the measurement. Though the intensity of light must be improved a little more, the array of highbrighted LED can generate enough light to trace the moving particle.","subitem_description_type":"Abstract"}]},"item_3_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{},{}],"names":[{"name":"クロカワ, ジュンイチ"}]}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"181","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40017976","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=40017976"}],"names":[{"name":"黒川, 淳一"}]}]},"item_3_relation_12":{"attribute_name":"ISBN","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"9784998093220","subitem_relation_type_select":"ISBN"}}]},"item_3_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Yokohama National University, Yokohama, Japan"},{"subitem_text_value":"Yokohama National University, Yokohama, Japan"},{"subitem_text_value":"Yokohama National University, Yokohama, Japan"}]},"item_3_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":"Matsui, Jun"}],"nameIdentifiers":[{"nameIdentifier":"16758","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kurokawa, Junichi"}],"nameIdentifiers":[{"nameIdentifier":"181","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40017976","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=40017976"}]},{"creatorNames":[{"creatorName":"Imamura, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"16760","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-09-16"}],"displaytype":"detail","filename":"B-115.pdf","filesize":[{"value":"498.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"B-115.pdf","url":"https://ynu.repo.nii.ac.jp/record/3828/files/B-115.pdf"},"version_id":"ed656695-a5a2-4c1a-af7f-49268bbea521"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"PTV-Measurements of Flow in a Low Specific Speed Pump","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"PTV-Measurements of Flow in a Low Specific Speed Pump"}]},"item_type_id":"3","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-09-17"},"publish_date":"2008-09-17","publish_status":"0","recid":"3828","relation_version_is_last":true,"title":["PTV-Measurements of Flow in a Low Specific Speed Pump"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T21:39:13.248629+00:00"}
