Two-dimensional rectangular ducts are adopted, and the Navier–Stokes equations with a detailed chemical kinetic mechanism are solved by using direct numerical simulations. In this study, we focus on the effects of the initial pressure of hydrogen and the position of the obstacles on the ignition mechanisms. Our results demonstrate that the presence of obstacles significantly changes the spontaneous ignition mechanisms producing three distinct ignition mechanisms. In addition, the position of the obstacles drastically changes the interaction of shock waves with the contact surface, and spontaneous ignition may take place at a relatively low pressure in some obstacle positions, which is attributed to the propagation direction and interaction timing of two reflected shock waves.","subitem_description_type":"Other"}]},"item_7_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Accepted: 2015-01-17","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: PA1510061000","subitem_description_type":"Other"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_7_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.1016/j.jlp.2015.01.020"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1016/j.jlp.2015.01.020","subitem_relation_type_select":"DOI"}}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0950-4230","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10860951","subitem_source_identifier_type":"NCID"}]},"item_7_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"},{"subitem_text_language":"en","subitem_text_value":"University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Yokohama National University"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Morii, Youhi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Terashima, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Koshi, Mitsuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shimizu, Taro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Spontaneous ignition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Hydrogen safety","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Detailed chemical kinetic model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Computational fluid dynamics","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Numerical study of the effect of obstacles on the spontaneous ignition of high-pressure hydrogen","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Numerical study of the effect of obstacles on the spontaneous ignition of high-pressure hydrogen","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-08-12"},"publish_date":"2015-08-12","publish_status":"0","recid":"22560","relation_version_is_last":true,"title":["Numerical study of the effect of obstacles on the spontaneous ignition of high-pressure hydrogen"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:19:06.118466+00:00"}
