Because the diffracted shock waves are often generated by the explosions of combustible gases to cause serious damages against human race and surrounding buildings. The maximum pressure behind reflected shock wave is one of the most important parameter and this report is concerned with the evaluation of maximum pressure, which might be a function of Mach number of the shock wave, distance from a source of the shock wave, initial pressure of the gas, and initial diameter of the shock wave, etc. In this study, a detonation-driven shock tube of 14 m long and 50 mm diameter is used to generate a strong shock wave of propagating Mach number M_S=3.0〜5.2. The shock wave is diffracted from an open end of the shock tube of 25 mm diameter and reflected from a cylindrical reflector of 50 mm diameter. These phenomena are observed using color-schlieren optical techniques and the pressure histories at the stagnation point of the reflector are simultaneously measured. As a result, (i) The behaviors of the diffracted shock wave and complicate flow-fields behind reflected shock wave are observed. (ii) An empirical equation to calculate the maximum pressure behind reflected shock wave is estimated by the results of experimental and numerical simulation.","subitem_description_type":"Abstract"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"社団法人日本機械学会"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03875016","subitem_source_identifier_type":"ISSN"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"OBARA, Tetsuro"},{"subitem_text_value":"OHYAGI, Shigeharu"},{"subitem_text_value":"KATOH, Hajime"},{"subitem_text_value":"ARIGA, Yousuke"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A3000055"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学大学院理工学研究科"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2002-04"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小原, 哲郎"},{"creatorName":"オバラ, テツロウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"大八木, 重治"},{"creatorName":"オオヤギ, シゲハル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"加藤, 肇"},{"creatorName":"カトウ, ハジメ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"有賀, 洋介"},{"creatorName":"アリガ, ヨウスケ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A3000055.pdf","filesize":[{"value":"953.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A3000055.pdf","url":"https://sucra.repo.nii.ac.jp/record/12646/files/A3000055.pdf"},"version_id":"13a87475-26b0-4331-b5c3-1a4fa21afde9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Shock Wave","subitem_subject_scheme":"Other"},{"subitem_subject":"Detonation Wave","subitem_subject_scheme":"Other"},{"subitem_subject":"Compressible Flow","subitem_subject_scheme":"Other"},{"subitem_subject":"Flow Visualization","subitem_subject_scheme":"Other"},{"subitem_subject":"Diffraction","subitem_subject_scheme":"Other"},{"subitem_subject":"Reflection","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"開放端から放出された衝撃波に関する実験と数値シミュレーション(流体工学,流体機械)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"開放端から放出された衝撃波に関する実験と数値シミュレーション(流体工学,流体機械)"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-09-10"},"publish_date":"2007-09-10","publish_status":"0","recid":"12646","relation_version_is_last":true,"title":["開放端から放出された衝撃波に関する実験と数値シミュレーション(流体工学,流体機械)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:56:53.836488+00:00"}
