In his theory he assumed that the surface energy is symmetrical about the center of a drop, and the symmetry itself prevents the theory from dealing with multi-lobed waves. In this report, an equation for multi-lobed waves induced on a rotating drop by sound waves is shown. The wave equation is first derived on the assumption that the acoustic radiation pressure around a drop is constant. Then the effects of the deformed drop on the radiation pressure surrounding the drop are considered. In addition, the equation for the relationship between the radiation pressure and a drop that becomes oblate due to the radiation pressure is obtained. The two equations are compared with the results of both ground experience and flight experience and it is shown that good agreement exists between the theoretical prediction and the experimental results.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0001440000","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 TR-1337","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":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"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 宇宙研究グループ"},{"subitem_text_value":"横浜国立大学"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Space Technology Research Group"},{"subitem_text_language":"en","subitem_text_value":"Yokohama National University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"上村, 平八郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山中, 龍夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kamimura, Heihachiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamanaka, Tatsuo","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":"2020-01-27"}],"displaytype":"detail","filename":"naltr0001337.pdf","filesize":[{"value":"566.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr0001337.pdf","url":"https://jaxa.repo.nii.ac.jp/record/40183/files/naltr0001337.pdf"},"version_id":"6587172b-9c78-4f2a-9f0c-b353cae3ab82"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"回転液滴","subitem_subject_scheme":"Other"},{"subitem_subject":"音波","subitem_subject_scheme":"Other"},{"subitem_subject":"多葉波","subitem_subject_scheme":"Other"},{"subitem_subject":"音響放射圧","subitem_subject_scheme":"Other"},{"subitem_subject":"扁平度","subitem_subject_scheme":"Other"},{"subitem_subject":"表面張力","subitem_subject_scheme":"Other"},{"subitem_subject":"無接触保持装置","subitem_subject_scheme":"Other"},{"subitem_subject":"宇宙材料製造","subitem_subject_scheme":"Other"},{"subitem_subject":"微小重力","subitem_subject_scheme":"Other"},{"subitem_subject":"音響浮揚","subitem_subject_scheme":"Other"},{"subitem_subject":"rotating drop","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sound wave","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"multilobed wave","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"acoustic radiation pressure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ellipticity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"surface tension","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"contactless retainer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"space material processing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"microgravity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"acoustic levitation","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"定在波中における液滴の挙動","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"定在波中における液滴の挙動"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"40183","relation_version_is_last":true,"title":["定在波中における液滴の挙動"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T19:16:50.591163+00:00"}
