In case of single passage of normal shock wave through 2-D circular helium bubble floating in air it have already been clarified that the vortical motion divides the bubble into two parts and the mixing is enhanced. In this report, the influence of round-trip passage of normal shock wave on mixing state is numerically investigated by TVD formulated finite differential method for Navier-Stokes equation and chemical species mass conservation equations. The interaction of contra-directional vortices by forward propagation of incident shock wave and backward one of reflected wave from rigid wall attracts much attention. The general mixing process consists of the first division of helium bubble into two semicircular parts by the forward passage and the second division into four parts. Since the existence of time delay to start vortical motion after shock passage disturbs the interaction of the backward passage on first vortex, a shorter interval of two passages presents slow formation of the small four bubbles. Two contradictory features are observed after the backward passage, a slight mixing suppression estimated from mean concentration distribution and the elongation of boundary line separating air and helium.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0045948048","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL SP-57","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-260X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"防衛大学校 システム工学群　航空宇宙工学科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Defense Academy Department of Aerospace Engineering, School of Systems Engineering"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小幡, 茂男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Obata, 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":"2020-01-24"}],"displaytype":"detail","filename":"nalsp0057048.pdf","filesize":[{"value":"337.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0057048.pdf","url":"https://jaxa.repo.nii.ac.jp/record/38269/files/nalsp0057048.pdf"},"version_id":"7868202f-7a77-4275-84da-db1a3c70584d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"数値シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"気体混合過程","subitem_subject_scheme":"Other"},{"subitem_subject":"衝撃波","subitem_subject_scheme":"Other"},{"subitem_subject":"Navier-Stokes方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"TVDスキーム","subitem_subject_scheme":"Other"},{"subitem_subject":"密度分布","subitem_subject_scheme":"Other"},{"subitem_subject":"圧力勾配","subitem_subject_scheme":"Other"},{"subitem_subject":"保存方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"質量保存","subitem_subject_scheme":"Other"},{"subitem_subject":"研究開発","subitem_subject_scheme":"Other"},{"subitem_subject":"2次元モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"泡","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gas mixing process","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"shock wave","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Navier-Stokes equation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"TVD scheme","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"density distribution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"pressure gradient","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"conservation equation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mass conservation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"research and development","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"2 dimensional model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"bubble","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"反射する垂直衝撃波による気体混合の数値解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"反射する垂直衝撃波による気体混合の数値解析"}]},"item_type_id":"5","owner":"1","path":["1891","1915"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"38269","relation_version_is_last":true,"title":["反射する垂直衝撃波による気体混合の数値解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:42:29.917174+00:00"}
